Szentendre Castle Church is the oldest building of the city, originally built between 1241 and 1283. Its present day plan was finalised when it was rebuilt in Gothic style in the 14th century. It was again renovated, this time in a Baroque style by the Zichy family in 1710. Its present day outlook was completed between 1742 and 1751.
The building is 200 m2 large, its tower is 29 meters tall. Its walls are supported by buttresses which are typical to Gothic architecture. On the buttress near the tower, there is a sun clock from the 1300's, a unique piece from the history of Hungary. The visitor can step inside the church through Gothic stone doors.
Looking up in the interior of the building, we can see three giant, Baroque rib vaults. The three side altars are dedicated to the Virgin Mary, Three Kings and Saint Andrew. The main altarpiece depicts the Baptism of Jesus by Saint John. The painting is a work of Carolus Schöfft from 1818. Above the altar an all seeing eye watches over the church. Interestingly, the biblical figures of the frescoes, instead of the usual, authentic settings, are depicted in the landscape of Szentendre.
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.
