The Cathedral of St. Anastasia (Croatian: Katedrala sv. Stošije) is the Roman Catholic cathedral of Zadar, Croatia, seat of the Archdiocese of Zadar, and the largest church in all of Dalmatia (the coastal region of Croatia).
The church's origins date back to a Christian basilica built in the 4th and 5th centuries, while much of the currently standing three-nave building was constructed in the Romanesque style during the 12th and 13th centuries. The site has been submitted to UNESCO's Tentative List of World Heritage Sites. [source]
