Ankara Castle

Ankara Castle is a monument of the city and current capital of Turkey. The exact details of the build are unknown; however, it is thought to have been built after the destruction of Ankara by the Persians around 622. The build is said to have been built by using reused masonry, a form of ancient recycling.

The architecture uses common concentric rings that were common in the fortress for defence, with the inner line of the wall with closely spaced towers with an outer line of walls with towers approximately 40 metres apart.
