Château de Pibrac was built in 1540 to the site of older castle. It was damaged during the Revolution in 1794 and restored in 1887. The renaissance style residence is built of red brick. The castle itself consists of an old body and wings. The north wing is flanked by a round tower with terrace and has a staircase. The castle park, open to the public, was designed by the landscape architect Eugène Bühler in 1897.
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.
