The city of Hvar has a long and distinguished history as center for trade and culture in the Adriatic. A commune, part of the Venetian Empire during the 13th to 18th centuries, it was an important naval base with a strong fortress above, encircling the town walls and protecting the port. Cultural life thrived as prosperity grew, and Hvar is the site of one of the oldest surviving theatres in Europe, opened in 1612. The seven-hundred-year-old walls still survive, as do many of the noble houses and public buildings from 15th – 17th centuries.
