Rawa Mazowiecka Castle is a Gothic style square formation castle located in the lowlands of the river Rawka and the river Rylka. Currently it is a renovated ruin.
According to the scriptures of Jan Długosz, the castle was built by Casimir III the Great, and the stronghold's function was to protect the southern borders of Masovia. Although reconstruction efforts have been raised by Franciszek Lanckoroński, the reconstruction was stopped, most likely due to the Partitions of Poland, after which the Prussian authorities ordered to deconstruct the ruins, only keeping the tower. The rest of the brick material was used for nearby housing. Currently the renovated tower is open to tourists, and the outline of the castle's former square formation has been reconstructed around the tower.
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.
