Right next to the archaeological museum is this cultural gem, awarded the Council of Europe's museum prize in 2005. We'd say it is one of the finest Greek museums outside of those in Athens itself, and arguably has the best collection of Byzantine artifacts in the country. It expertly presents these treasures, which range from icons to jewelry and embroidery, including a standout 9th-century enamel-and-gold filigree bracelet, alongside erudite and interesting wall text (translated into English). A room upstairs shows how pottery was made. Another houses expressive biblical-themed frescoes from 4th to 6th century barrel vaulted tombs. The gift shop sells books on Byzantine culture, museum reproductions, and postcards.
