Château de Parthenay was built during the 13th century whose remains are still visible to this day. The castle was built on a rock by the side of the river. A citadel was built around the castle which was only accessible through the Saint Jacques gate. The gate and the city walls are still largely intact. There is another gate at the other side of the city, the Tour de l'Horloge gate. Both gates have characteristic almond-shaped towers. In total, the citadel has over 30 defensive towers, 4 entrance gates and a defensive wall with a length of over 1km.
References: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.
