The Xylokerkos or Xerokerkos Gate , now known as the Belgrade Gate (Belgradkapı), lies between towers 22 and 23. Alexander van Millingen identified it with the Second Military Gate, which however is located further north. Its name derives from the fact that it led to a wooden circus (amphitheatre) outside the walls. The gate complex is approximately 12 m wide and almost 20 m high, while the gate itself spans 5 m. According to a story related by Niketas Choniates, in 1189 the gate was walled off by Emperor Isaac II Angelos, because according to a prophecy, it was this gate that Western Emperor Frederick Barbarossa would enter the city through. It was re-opened in 1346, but closed again before the siege of 1453 and remained closed until 1886, leading to its early Ottoman name, Kapalı Kapı ("Closed Gate").

Very well preserved historical site which is symbol of one of the greatest war victory

Photos other than the main photo (the gate) are walls that nearby.

This structure, which is close to the sea side of the Istanbul land walls, is also called Theodoros.

Huge history, good renovations. Vegetables being grown in the moat 😃.

Not much to see, but interesting for people from Belgrade, Serbia.

Construction was ongoing in the path from the golden gate and it's a bit of a trek to get here. It's a cool place of history but needs to be taken in with the adequate contextual walls

Not too much to see. The access to the walls top is blocked, but it can be accessed if you are brave and skilled enough.

One of the best turistic places in Istanbul.

Its looks nice. What is the story of this place?
