Near the port of Brindisi a set of monumental stairs climb from the waterfront to a small square with a column and the remains of another. These are the Roman Columns of Brindisi, the origins and purpose of which are still unknown. Historically, it’s believed the columns marked the end of the Via Appia, a massive Roman road that connected the capital to the port of Brindisi, or the Via Traiana, a later alternative to the Via Appia. Only one remains, the second having been misappropriated and removed to the neighbouring town of Lecce.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
