The castle is composed of an inner line of walls with closely spaced towers that encloses an area of about 350 m by 150 m, and an outer line of walls with towers some 40 m apart. Both sets of walls were constructed using large quantities of reused masonry. The exact dates of their construction are uncertain, but both postdate the capture and destruction of Ankara by the Persians in, probably, 622 AD (Foss considers that the inner walls may date from the reign of
Constans II; the outer walls are generally believed to have been erected slightly later.). Ankara asv2021-10 img30 Kale and Citadel.jpg|Aerial view of Kale (
