It takes roughly an hour to drive from Khiva to Biruniy and a further hour to get to Ayaz

Looking up at Ayaz qala 2 from the south west.
Note the rectangular entrance and the long sloping staircase.



View of Ayaz qala 2 from the battlements of Ayaz qala 1.

In this respect the architecture of Ayaz qala 2 is quite unique. It was built of rectangular mud bricks on a foundation of compacted clay known as paqsa. The upper parts of the outer walls appear to have been crenulated. The building was fortified with low battlements and a single row of arrow slits running around the entire perimeter. The almost square entrance chamber is on a lower level than the main fort, the latter containing a number of rooms including one with a vaulted ceiling at the north eastern end.
