Church of St. Donatus

The Church of St. Donatus in Zadar is a round Catholic church in the heart of the Croatian city and one of its best-known symbols. It is the largest pre-Romanesque building in Croatia and the most recognisable landmark on Zadar's old-town peninsula.

Where is it and what does it look like?

The rotunda stands on the north-eastern part of the former Roman forum, right in the old town. From a distance it reads as a massive cylindrical volume with a tall, plain body and an ambulatory inside. It belongs to the centralised building type typical of Carolingian-era Europe. On a map, look for the square that also holds the remains of the Roman forum and several neighbouring churches.

Who built it, and when?

The founder was Bishop Donatus of Zadar. Construction is usually placed around the turn of the 8th and 9th centuries, with completion in the early decades of the 9th; sources differ on exactly when work began, so the 9th century is the safe shorthand. The church was originally dedicated to the Holy Trinity. The bishop's name became the church's name only in the 15th century, and it has stayed that way ever since.

Why are Roman stones visible in the walls?

The builders did not haul material from far away. They reused pieces of the ancient forum: Roman columns, stone blocks and inscribed slabs were set into the foundations and lower walls as spolia. Visitors therefore see two eras in one place, ancient Zadar and early medieval Dalmatia, which is a big reason the building appeals to history and architecture fans.

How is the church used today?

The interior is austere and tall, and its acoustics make the building work mainly as a concert hall. Early music and other musical events are staged here. The rotunda is about 27 metres high and was originally covered by a dome.
