Located 450 km from Athens, 290 kilometres from Thessaloniki and 80 km from the port of Igoumenitsa in the Ionian Sea. Founded by the Byzantine Emperor Justinian in the 6th century AD, the town flourished following the Fourth Crusade, when many wealthy Byzantine families fled there in the early 13th century following the sack of Constantinople. Ioannina has a wealth of attractions and museums: The Islet of Pamvotis lake, the Island Museum, the National Archaeological Museum, the castle located in the center of the town, the Fethiye Mosque located in Its-Kale Fortress, the Aslan Pasha Ottoman Mosque, the Old Ottoman Library, the Byzantine Museum, the Municipal Gallery of Ioannina, and the Jewish Synagogue. 10 km south of the city lies the Pavlos Vrellis Greek History Museum, a wax museum which covers events and personalities from Greek history, established in 1995 and it is the result of the personal work of one man. Ioannina is famous throughout Greece for its silverwork and has many shops selling silver jewelry and decorative items.
