A wander around Akhaltsikhe's rabati (old town), with its multicultural architecture, is well worthwhile. This district is on a hill on the north side of the Potskhovi, just west of the bridge. Rare examples of darbazebi (traditional Georgian houses) cluster around the castle, which was built in the 12th century and houses a mosque from 1752 and the ruins of a medrese (Islamic school). The rabati also has a synagogue, an Armenian church and a Catholic church.
