About Hvar

Hvar is an island off the coast of Croatia with a population of about 11,000 people (2011). Imposing fortifications hover above the fluid blend of grey stone and orange cascading roofs. The remains of walls built by a long list of invaders descend towards the wide promenade edging the brilliant blue sea and the quaint fishing harbor. Marble streets reveal one of the largest squares in Dalmatia, the prized Cathedral of St. Stephen, and the Renaissance theatre.
