Sultan Yildirim Bayezit built this fortress in 1393 on the ruins of a Byzantine temple dedicated to Zeus. It's much smaller in size when you compare with Rumelihisari fortress lying on the European side, just on the opposite. Today, it's an open air museum.

Rumelihisari (Rumeli Fortress)

Rumelihisar fortressSultan Mehmet the Conqueror built Rumeli Fortress in four months only and directly opposite to Anadoluhisari fortress in 1452 in preparation for the final attack on Constantinople (modern Istanbul), which led to the downfall of the Byzantine Empire. Today, the fortress hosts many concerts and dramatic performances in its amphitheatre usually during the summer months. The fort is open to the public as a museum everyday, except on Wednesdays.

Yedikule Hisari (Seven Towers dungeons)

This seven towered fortress was built in the time of Sultan Fatih Mehmet to protect the treasury. In Murat III's reign, the treasury protected at Yedikule was relocated to the Topkapi Palace and Yedikule began to be used as a dungeon. The place of imprisonment of many foreign ambassadors and Ottoman statesman, as well as a place of execution for some, the fortress was last used as a prison in 1831. It than became a dwelling for the lions of Topkapi Palace, and later gunpowder manufacturing place. Today the fortress is a museum, also hosting open air concerts in its inner courtyard during the summer months.

Galata Kulesi (Galata Tower)

Galata towerA 55 meter tower providing a panoramic view of the old town, Galata Kulesi was built in the 14th century by the Genoese as part of the defense wall surrounding their district of Galata directly opposite Byzantium (Constantinopolis). The Genoese used to trade with the Byzantines and the tower was used for the surveillance of the Harbor in the Golden Horn. After the conquest of Constantinople by Mehmet II it served to detect fires in the city. The tower now houses a restaurant. Today there is an elevator but there are still three more floors to climb by stairs to get on the panoramic terrace. It's open from early morning until late afternoon everyday.

Kiz Kulesi (Leander's Tower - Maiden Tower)

KizkulesiA 12th century stone tower erected on a rock at the entrance of the Bosphorus by Byzantine Emperor Manuel Komnenos. This tower, which has served as a prison and a lighthouse, became the source of many legends in ancient days, such as Leander's or Maiden's. It's now open to the public as a cafeteria & elegant restaurant which hosts concerts and meetings as well. Transportation to the Tower is made by private shuttle boats from both shores of the Bosphorus.

Beyazit towerIt was built by architect Senekerim Kalfa of the Balyan family in 1828 under the reign of Mahmud II. The tower is 85 meters in height and has four floors, 180 steps staircase to the top. It was built over the Golden Horn to detect fires in Istanbul, baskets during the day and large red, green and white lanterns in the evenings were hung on the tower to indicate that there was a fire in the city. It's still used for the same purpose today. Unfortunately it's close to the public at the moment, and stands in the grounds of University of Istanbul.

Dikilitas (Egyptian Obelisk)

Egyptian ObeliskIt was originally erected in the 16th century B.C. by the Pharaoh Thutmosis III in honor of the God of Sun Amon Ra in the city of Teb, Egypt, in front of the temple of Luxor. Brought to Istanbul by emperor Theodosius I in 390 A.D. for the decoration of the ancient Hippodrome. The approximately 19 meter high obelisk is covered on all four sides with hieroglyphic pictograms and stands on a marble base with many friezes depicting the Emperor and his family in the Hippodrome. After decoding the hieroglyphs it has been discovered that last 5 or 6 meters of the Obelisk is missing from the bottom, probably was broken during the transportation.

Stone Obelisk (Orme sutun)

The column was erected by Constantine VII, known also as Porphyrogenetus, around 944 AD for the decoration of the Byzantine Hippodrome. It was made of limestone blocks and completely covered with bronze slabs bearing inscriptions which were dedications made to his grand father Basileus I. Unfortunately all bronze slabs were removed during the rule of the 4th Crusade who melted them to make coins and weapons, therefore none of them survived until our days. The column is about 32 meters high and rests on a small marble base.

Serpentine Column (Burmali Sutun)

Originally this column was erected in 479 B.C. in front of Temple of Apollo in Delphi, Greece, to commemorate the naval victory of the Greeks over the Persians and to show their respect to Apollo for winning the battle after consulting his oracle. The bronze column was formed by 3 intertwined snakes and names of the 31 Greek city-states that participated in the war were written on them. It's also said that there was a big golden pot on top of the snake heads. The column was brought to Constantinople in the 4th century AD by Constantine I, for the decoration of the Hippodrome. The Serpentine column was originally 8 meters high but today only 5.30 meters left because nobody enjoyed this statue here being the snakes representation of the devil, so everybody took a piece off to destroy it. Therefore, the 3 snake heads were also destroyed and only pieces of one of the heads is found during the excavations and it was taken to the Archaeological Museum.

Goths Column (Gotlar Sutunu)

The column stands at the outer courtyard of Topkapi Palace, in Gulhane Park, and surrounded by trees. It's one of the oldest columns from the Roman period, which was erected probably in the 3rd or 4th centuries AD, carved from a single piece of stone and decorated with a Corinth style capital containing an eagle relief. Because of the inscriptions mentioning the victory over the Goths, it's called as Goths Column. The column is 15 meters high and rests on a small base.

Cemberlitas Column (Constantine Column)

The column, known as Cemberlitas (column with rings) in Turkish, was brought to Constantinople from the Temple of Apollo by Constantinus I between 325-328 AD. There was a statue of Apollo on top which was replaced by a cross during Christianity. The column symbolizes also the end of Pagan tradition on the Byzantine lands. It was erected in the middle of an oval square known as Forum Constantini, located on the second hill of the city. The cross was removed after the Conquest of Constantinople during the Ottoman period. The 35 meter high column was damaged by big fires and weather conditions during the ages so Sultan Mustafa II re-enforced the column with iron rings. The marble capital is from the 12th century and the reinforcing pedestal from the 18th. Today the Metropolitan Municipality is carrying restoration works of Cemberlitas column.

Marcianus Column (Kiz Tasi)

The column was erected around 450 AD and dedicated to the Byzantine Emperor Marcianus. It's made of 17 meter-high granite and rests on a marble base. The Corinthian style base is decorated with a relief depicting angels (or victory goddess) therefore it was called "Kiz Tasi" by the local people, meaning "Maiden's Stone" in Turkish. Today the column stands at Fatih district of Istanbul and the Metropolitan Municipality is restoring it.

Arcadios Column

The column is located at Cerrahpasa neighborhood. It was erected in the 5th century AD by Theodosius I and dedicated to Arcadios with a statue on top. According to old sources and travelers, the column was about 50 meters high and decorated with friezes describing victories against Barbarians, but today only the pedestal remains. The column was badly damaged during the earthquakes and it was strengthen by banding metal rings during the Ottoman period.

Theodosius Triumphal Arch

Theodosius I erected a huge Triumphal Arch which was crowned with the statue of the emperor and a column in the center of old Forum Tauri (today's Beyazit Square) in the 4th century AD. Some marble pieces of the Arch can still be seen today in its original location but the column and monumental fountain were destroyed by an earthquake in 557 and completely vanished around 16th century being used as construction material. Some of the pieces were used in the construction of a Turkish Bath next door, of which friezes can still be noticed today on its walls and base.

Million Stone

It's located at Sultanahmet neighborhood, in the center of old city. The Million Stone was always put in the center of the city and distances to all corners of the Byzantine Empire were once measured starting from this point. The stone was erected under the reign of Constantine the Great around 4th century AD in the northeastern corner of Augusteion Square, marking the starting point of an extensive road network.

Aqueduct of Valens

This is a Late Roman and Early Byzantine period aqueduct built probably around 4th century AD connecting two hills (out of seven) of ancient Constantinople over this little valley. It's known as the Aqueduct of Valens, and today local people call it as Bozdogan Kemeri (Arch) in Turkish. Originally it was used to bring water to Istanbul from the springs of Belgrade forest, about 30 km north of the city.

During the late Byzantine period it wasn't used much and fell into ruins, than restored by the Ottomans after the Conquest of the city and served for some time to carry water again. Over the centuries, it was badly damaged because of disuse and roads and buildings constructed on and around it. Today only bits and pieces left from the original aqueducts on its way from the forest to the city center, and in Sarachane neighborhood there is a 900 meter long part of it, namely Bozdogan arch. The Municipality of Istanbul started the restorations in 1998.

Tower of Justice (Kasr-i Adl)

The tower is a part of Topkapi Palace and stands in its second courtyard, right above Council Chamber next to the Harem complex. It was built under the reign of Sultan Mehmet II and used as a watch tower and surveillance of the Golden Horn. Several restorations were made to the tower and the last one was made by the architect Sarkis Balyan. The name of the tower comes from the Divan Room (Council Chamber), where there was a small window on the wall from which the sultan himself (or his spy) used to listen the Viziers behind a curtain and if he didn't like any thoughts than ordered to kill or imprison that member of the Council, so this was of course the justice of the sultan.

Dolmabahce Clock Tower

The Clock Tower was built right after Dolmabahce Palace by Sultan Abdulhamid II between 1890-1895, at the entryway of the Palace. The architect was Sarkis Balyan again. The clock has a European design and is 27 meter high with four floors, and on two sides the Tugra (monogram) of the sultan can be noticed.
