The collections in the well-preserved Aslan Mosque, now the Municipal Museum, recall the three communities (Greek, Turkish, Jewish) that lived together inside the fortress from 1400 to 1611. The vestibule has recesses for shoes, and inscribed over the doorway is the name of Aslan Pasha and "there is only one god, allah, and muhammed is his prophet." The mosque retains its original decoration and mihrab, a niche that faces Mecca. Exhibited around the room are a walnut-and-mother-of-pearl table from Ali Pasha's period, ornate inlaid hamman (Turkish bath) shoes on tall wooden platforms, treasure chests, traditional clothing, a water pipe, and a collection of 18th- and 19th-century guns.
