The Church of St. Donatus is a church located in Zadar, Croatia. It was originally named Church of the Holy Trinity, but eventually in the 15th century it changes its name to Church of St. Donatus, as a dedication to Donatus who started building the church in the 9th century. Today it is the largest Pre-Romanesque building in Croatia. The use of the church has varied during its lifetime; during the rule of the Republic of Venice it was a warehouse, as well as during the French occupation and under the Austrians. After the city was annexed to Yugoslavia, it served as an archaeological museum for a short period of time. Today it’s the site of many musical evenings due to its amazing sound reverberations, interior and acoustics.
