    Palaces and Mansions in and around İstanbul

    Dolmabahçe Palace 

    Located on the European side of the Bosphorus in İstanbul, Dolmabahçe was originally a bay. In the 17thcentury, under the reign of Sultan Ahmet I and his successor Osman II, the bay was gradually filled in order to enlarge the imperial garden. This process led to it becoming known as the ‘dolmabahçe’, literally meaning the filled garden. Also in the 17th century a palace complex known as the Beşiktaş Waterfront Palace was built inside of the garden. However, in the 19th century, during the reign of Sultan Abdülmecid II, the initial wooden palace was demolished, and the Dolmabahçe Palace was built in the grounds as the main imperial palace. The royal family moved there, abandoning their long-time home at Topkapı Palace in Fatih. Dolmabahçe Palace was built by the famous Balyan family, by Nikoğos and Karabet Balyan, and it was one of the best examples of that Neo-Ottoman style, that merged Italian and French Renaissance artistic styles both with Baroque and with Ottoman architecture.

    Topkapı Palace

    Situated in the historical peninsula of İstanbul, in Fatih District, Topkapı Palace served as both administrative headquarters and imperial residence during the most glorious period of the Ottoman Empire. The first buildings of the Palace were built between 1451 -1481, just after the conquest of İstanbul by Fatih Sultan Mehmet. Opening onto the famous Ayasofya Grand Mosque square, the Imperial Gate, Bab-I Humayun, leads to the first court, where the Hagia Irene Church and various pavilions along with the oldest building, the Çinili Köşk are to be found. The first court leads to the second court with the Middle Gate, Bab’us Selam, where the palace buildings can be found. A third court opens onto the Harem Section, where the imperial family lived with their extended families. And finally, the fourth court that is entered through the Treasury Room, with a covered path is located at very end of the complex.

    Küçüksu Pavilion

    Located on the Asian shore of Bosphorus, in today’s Küçüksü neighbourhood in Beykoz, the area where Küçüksu Pavilion was built was initially enjoyed as gardens by the imperial family. At the beginning of the 18th century, during the reign of Sultan Mahmut firstly a two-storey timber palace was built. The first palace was also used by Sultans Selim III and Mahmut II, however, later, during the reign of Abdülmecid in the 19th century, the wooden pavilion was demolished in order to build a new one. The Küçüksu Pavilion was designed and built by Nikoğos Balyan, a member of the famous Balyan family. It is relatively small pavilion built for short stays for the country excursions of the Sultans or for hunting trips to the woodlands nearby.

    Ihlamur Pavilions

    Located in today’s Beşiktaş district of İstanbul, the Ihlamur valley was once a popular picnic site in the 18th century. In the 19th century, however, during the reign of Sultan Abdülmecid, along with many other palaces and pavilions commissioned to be built by the Balyan Family, Ihlamur Pavilions were also constructed. The pavilions consist of two buildings, Ceremony Pavilion and Retinue Pavilion both display baroque features.

    Aynalıkavak Pavilion

    The fourth largest palace in İstanbul, following Dolmabahçe, Topkapı and Üsküdar, Aynalıkavak Pavilion is the only remaining building of the Aynalıkavak Palace. Located on the shore of Golden Horn near the old shipyard, it was also known as the Tersane (the shipyard) palace. The first buildings of the complex were built in the 17th century, however, by the end of the 18th century, due to many new additions, the pavilion became known as a palace. Aynalıkavak Pavilion is one these buildings, thought to originally date from the reign of Sultan Ahmet III. It was Sultan Selim III, who tore down many of the buildings of the palace in order to enlarge the shipyard. The same Sultan also spent the majority of his time at the Aynalıkavak Pavilion, where he composed many of his Classical Ottoman music pieces. Dedicated in his honour, some couplets were by engraved on the windows by a famous Ottoman calligrapher.

    Chalet Pavilion

    Chalet (Şale) kiosk is one of the many buildings of the Yıldız Palace complex that was built in 1880 for Sultan Abdülhamid II who left Dolmabahçe Palace, and settled at the Yıldız Palace. The palace was extended by additional buildings designed and built by famous Italian architect of the era, Riamonda D’Aronco. The Şale Kiosk hosted many important visitors such as Winston Churchill, Charles de Gaulle and Kaiser Wilhelm II.

    Palaces and Mansions Outside of İstanbul


    İshak Pasha Palace

    İshak Pasha Palace is located 5 km east of Doğubeyazıt in the remote south east of the country, right on the Silk Route. It was built on one of the hills of a mountain, and is considered to be a unique example of the The Tulip Period of the 18th century. The architectural style of the complex is a mixture of Ottoman, Persian, Armenian and Seljuk traditions. The façades were decorated with cut stone and bas reliefs that represent artistic tradition of the Seljuks. Wood was also used as a decorative element, especially in to build the beams that were constructed as three-dimensional sculptures, having symbolic meaning in Turkish art.  The complex was completed in 1784 according to the script on the door of the Harem section, by İshak Pasha. İshak Pasha was the first person to discover and adopt a heating system inspired by the bath system. The building was severely damaged during the 19th century because of wars and an earthquake; nevertheless, in 1992 ministry of culture initiated a restoration program and later in 2000 the palace was inscribed to the UNESCO World Heritage tentative list.


    Hazeranlar Mansion

    One of the most beautiful examples of vernacular architecture of 19th century in the Ottoman Period, The Hazeranlar Mansion is located in Yalıboyu, in Amasya. The mansion was built in 1865 for Hazeran Hanım, who was a famous local woman. After it was renovated, the Mansion was converted into an ethnography museum in 1986.


    Safranbolu Houses

    Located in the north eastern of Türkiye, Safranbolu gives us the opportunity to study Ottoman Period residences dating from the 18th century in a town. Carved by rivers, the sloping geography of Safranbolu renders the town with the appearance of a series of terraces. The houses are generally two or three storey buildings built with a combination of wood and stone. The ground floors were built with stone, as was the case with many of the 18th century Ottoman houses. Supported with buttresses, the upper storeys are spacious despite their small lots. Because the upper floors were built in order to let in the maximum amount of sunlight, the axes of the houses are slightly shifted, between storeys, creating bizarre looking buildings with a slightly twisted appearance.

    Fortresses and Castles

    İstanbul City Walls

    Whether you approach İstanbul by the sea or by land the city walls are still a spectacular sight. Originally built by Byzantine Emperor Constantine the Great, the walls of Constantinople were a series of defences that encompassed the city on all sides and were the most famous such examples of the late antique and the mediaeval world. The Marmara walls secured the southern approach while the walls on the Golden Horn protected the northern side of the city. On the west, running approximately 6 km from the Sea of Marmara to the upper reaches of the Golden Horn, the land walls of Constantinople protected the city from its enemies and withstood many sieges for more than a thousand years until the city was conquered by the Ottomans in 1453. Partially standing today, this elaborate system of inner and outer walls, towers and moats, for the most part, were constructed by the Emperor Theodosius II in the first half of the fifth century. Restored by the Ottomans many times in the course of history, today the city walls of Constantinople are standing as the reminders of the glory of the imperial past of İstanbul.

    The Maiden’s Tower

    The Maiden's Tower - Kız Kulesi in Turkish, also known as Leander's Tower since the mediaeval Byzantine period, is a tower lying on a small islet located at the southern entrance of the Bosphorus close to the coast of Üsküdar in İstanbul. A customs station for ships coming from the Black Sea was built on a small rock in front of Üsküdar, ancient Chrysopolis. The islet was connected to the Asian shore through a defence wall, whose remains are still visible under the water. During the conquest of İstanbul in 1453 by the Ottomans, the tower was hosting a Byzantine garrison. The tower is often mistakenly referred to Leander's Tower in reference to the legend of Hero and Leander.

    Galata Tower

    The Galata Tower is one of İstanbul’s best known visual icons, dominating the districts of Beyoğlu and Karaköy from its elevated position.

    Although the exact construction date of the tower is not certain, it is possible that the tower was first built during the reign of Byzantine Emperor Justinian around 507 CE.  The tower was known as the Tower of Christ to the Genoese, while the Byzantines referred to it as the Great Tower. During the Genoese period, the tower took on its current shape, when the Galata neighbourhood was inhabited by merchants from Genoa, who ran a series of economic and trade posts in the Mediterranean and Black Sea.

    In 1509, the tower was damaged due to an earthquake, but was restored by Ottoman architect, Hayreddin, who was also the architect for the renovation of Sultan Bayezid II complex in Edirne. During the reign of Süleyman the Magnificent, the tower was used to accommodate prisoners who were sentenced to work at the Kasımpaşa Naval Dockyard. By the end of the 16th century, an observatory was added at the very top by the astrologer, Takiyüddin Efendi, but the tower become a prison once again during the reign of Sultan Murat III during 1546 and 1595.

    In the 17th century, the tower was briefly used by the Mehter Band, the Ottoman military band, and afterwards became a fire observatory in 1717. In 1794, a fire destroyed the tower, but it was restored again, and a cumba (protruding balcony) was added. In 1831, the tower was once again ravaged by fire, and once more restored, with the addition of two more floors and a conical-shaped tip.

    One of the interesting tales about the Galata Tower, is about the legendary Ottoman aviator Hezarfen Ahmet Çelebi. According to Evliya Çelebi, the famous Ottoman traveller, Hezârfen Çelebi flew from the top of the tower to Üsküdar with wings attached to his arms. Due to this spectacular feat, Sultan Murad Khan allegedly grew suspicious of the man and sent him to exile in Algeria.

    Today, the 66.90 m high tower serves as a tourist attraction, for visitors who enjoy a spectacular 360-degree view of İstanbul from the balcony.


    Diyarbakır Castle and Fortress

    Built first in the 3rd century during the Roman Period, the fortress of Diyarbakır has been expanded and fortified over the years.

Each civilisation that controlled the castle through the ages left its own imprint on the structure. These range from Xerxes I’s inscription from the 5th century BCE to a mosque built by Sultan Suleyman in the 15th century.

    Hoşap Castle

    Located in Van province on the Van-Hakkari road, Hoşap Castle was built in the 17th century. The name derives from beautiful water, and refers to the rivers nearby. The castle was built by the chief of Mahmudi tribe, Sarı Süleyman Mahmudi, and was used until the Tanzimat reforms of the 19th century that reorganized the provincial administration.


    The Maiden’s Castle

    Kızkalesi (Maiden’s Castle) is today situated on an island in Mersin Province, 300 metres away from the Mediterranean shore. First built in the 4th century BCE, the castle has been extensively renovated in the 13th century. The north and west side walls that were built by them are representative examples of authentic ashlar masonry.

    The location of the mosque suggests Sinan was also a great city planner as the mosque can be seen from considerable distances. This mosque is the culmination of his centralized-domed plans, the great central dome rising on eight massive columns in between which are impressive, recessed arcades, and this is the best example of any mosque with eight columns. There are elegant domes, reaching to the heavens, and towering, slim minarets that are characteristic of Ottoman mosque architecture.

This structure was destroyed by a fire in 476. The Basilica Cistern was built during the reign of Emperor Justinian I around 542. The cistern was used to store water for the Great Palace, surrounding buildings, gardens, courtyards, and palaces. The water collected in the cistern was delivered via 20 km long aqueducts from the Belgrade forest. Also known as the Yerebatan Palace (Yerebatan Sarayı) it has dimensions of 138 x 64 m and is supported by 336 columns which were brought here from various ruins.

It was the largest project undertaken by this famous architect. The structures of this line were damaged in the great floods of the same year and rapid repairs were carried out. For this reason, it is assumed that Kırkçeşme water system was completed in 1564. This system collects surface water around the Belgrade Forest in the north of İstanbul and brings into the city. The system consists of two main branches known as the western and eastern branches. The Long Aqueduct is in the western line. The whole system is comprised of 33 monumental aqueducts. The Long Aqueduct is one of these aqueducts and is made up of 97 arches. It is 711 metres in length and 25 metres high.

It is known that three of the arches are remains from the late Roman period. It is called Kırık (broken) or Eğri (curved) Aqueduct because it has a 90 degrees sharp turn after a certain point.

    The Valens Aqueduct

    The Valens Aqueduct is part of the ancient water supply system of İstanbul. Its remains form part of the most extensive water supply system known from the ancient world which is the Thracian Water Supply System. The water was delivered from the Thracian peninsula by the Valens Aqueduct to the heart of the city and reached as far as the Nymphaeum Maximum in the Theodosius Forum (Beyazıt Square) and finally filled the Binbirdirek Cistern.  The construction was completed during the reign of Roman Emperor Valens (364-378). The original total length of the structure is estimated to be about 971 metres and it is 27 metres high. The system continued to operate throughout the mediaeval period, but the supply line was broken several times by earthquakes, and military invasions. In the15th century (during the period of Sultan Mehmet II) the aqueduct was integrated into the main water supply line of the city.

There are many historical Turkish baths, where people enjoy the ‘silver water’ of Bursa, coming from the legendary Mysian Mount Olympus.
