St Donatus Church, Zadar

Originally known as Holy Trinity, this cylindrical church dates to the 9th or 10th century. It was renamed in the 15th century for the bishop who likely commissioned it. It is in the center of old Zadar and is built on the ruins of an ancient forum. Those ruins include a Roman era sacrificial altar dedicated to Juno and Jupiter. It has been deconsecrated and often now used for concerts due to it excellent acoustics.
The 1st picture looks across the main square which was also the old Roman forum at the building's exterior.
The 2nd picture looks at column bases where you can see original engraving and some of the rubble from the forum.
The remaining 4 pictures are an attempt to show the circular space, as it is unusual to n my experience.Read more
