Lying quietly along the shore of the Marmara Sea, Boukoleon Palace (or Bucoleon) is one of Istanbul's most intriguing hidden relics. Once the grand seaside residence of Byzantine emperors, it was originally built in the 5th century by Emperor Theodosius II and later expanded by Emperor Theophilos in the 9th century. The name “Boukoleon” - meaning “bull and lion” - comes from a statue group that once stood proudly in front of the small harbor below the palace walls. Although time and tides have reduced it to ruins, the site remains one of the must-see places in Istanbul for those fascinated by the city's early imperial history.

Today, Boukoleon Palace offers a glimpse into a forgotten era when Constantinople's elite lived overlooking the Marmara waves. With fragments of arches, marble facades, and carved windows still visible, the site is a great place to visit on a walking tour of Istanbul, especially for travelers exploring the remnants of Byzantium beyond the usual attractions.

History and Significance of Boukoleon Palace

Originally known as the Palace of Hormisdas, the complex began as a residence of Emperor Theodosius II in the 5th century. Its transformation into one of Byzantium's grandest palaces came under Emperor Theophilos (829-842), who expanded it with new pavilions and a striking 300-meter-long façade facing the sea. The Boukoleon became the principal imperial residence until the 11th century, when the Komnenos dynasty shifted the court to the Palace of Blachernae in the northwest of the city.

During the infamous Fourth Crusade in 1204, the palace was stormed by Western knights led by Boniface of Montferrat. Chronicles describe the plunder of unimaginable treasures - “beyond end or counting” - and the capture of the Hungarian princess Margaret, whom Boniface later married. Though the empire eventually recovered, the palace’s glory never returned. Over time, it fell into disuse and decay, its stones slowly merging with the city’s old sea walls.

Things to See and Do in Boukoleon Palace

While the Boukoleon Palace is not yet a fully restored monument, its surviving structures still impress those who venture to the site. Visitors can view the remains of the sea-facing walls, marble window frames, and arched chambers that once overlooked the Marmara. The palace's dramatic location beside the ancient harbor makes it a rewarding stop for history enthusiasts and photographers seeking atmospheric ruins away from the crowds.

Plans are underway to transform the Boukoleon into an open-air museum, complete with a timber walking path, visitor center, and reflective pool designed to evoke its maritime past. Until then, visitors can admire the palace from the roadside and seafront walkway along Kennedy Avenue. Even fenced off, the site exudes a quiet majesty - a reminder of Constantinople’s early days as the seat of an empire that ruled both East and West.

How to Get There

Boukoleon Palace lies along Kennedy Avenue, between Sultanahmet and the Yenikapı area, overlooking the Marmara Sea. It's easily reached on foot from Sultanahmet Square - about a 10-minute walk downhill past the Arasta Bazaar and along the ancient sea walls. For those using public transport, the T1 tram stops at Sultanahmet, from where the site is accessible on foot. For visitors arriving by train, Sirkeci railway station is roughly 20 minutes away on foot. You can use the official TCDD Taşımacılık website to check schedules, compare routes, and purchase tickets for Turkey’s national and regional trains operated by TCDD. For a more streamlined experience (especially if you prefer an English interface or want to compare across countries), we recommend using Omio, which allows you to easily compare prices, schedules, and book train tickets across Turkey and the rest of Europe — all in one place. Drivers can park near the coast road or in the paid parking areas close to the Small Hagia Sophia Mosque. If you are looking to rent a car in Turkey I recommend having a look at Discover Cars, first, as they compare prices and review multiple car rental agencies for you.

"Bukoleon Palace Bukoleon Palace is a coastal palace built during the Byzantine period in Istanbul. It was founded in the 5th century, probably duringthe reign of Justinian I, and expanded by subsequent emperors. It was strategically located on the shores of the Sea of Marmara, co ected to the Great Palace complex of Constantinople. It served as a residence and ceremonial site for the emperors, particularly in the 9th and 11th centuries. It is believed to have taken its name from the bull and lion statues in its harbor. It lost its importance after the Latin invasion (1204) and was abandoned during the Ottoman period. Its ruins can be seen today near Çatladıkapı, but it has been largely destroyed. Restoration work is ongoing, and the palace is a significant example of Byzantine architecture...."

"Old palace built by Theodosius I. Under construction right now, as seen in the photos. Accessing the construction site is strictly prohibited and ifyou dont want to risk trouble with the local authorities you will adhere to the barbed wire fence. Sadly the reconstruction is severly underfunded and seems to have stalled. Much of the old places elements seem to have been removed. When the archeological work is go a be completed is intransparent. My thesis would be they dug this up to build a new road on top, for which they had to check the static condition of the ruins...."
