Aboa Vetus (Old Turku) is a museum of archaeological history. Originally, plans were for only Ars Nova, the contemporary art museum, but during its construction a number of structures and artifacts dating back to the Middle Ages were discovered, and the archaeological excavation that was commissioned eventually transformed into Aboa Vetus. The two museums were combined in 2004.
The ruins excavated in the Convent Quarter originate from the Middle Ages. In the midst of these ruins, museum visitors progress through the permanent exhibition, which focuses on the 15th century. The artefacts on display originate from the excavations carried out in the town quarter where the museum actually sits.

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.
