The Premontre monastery church of Zsámbék is a ruin of a Romanesque church in the town of Zsámbék, Pest County, Hungary. The construction of the church started in 1220.
The construction of the church started as a part of a Premonstratensian monastery. It was the third consecutive church standing at the same site. The construction was completed in the 13th century. It was a private family church, built by a single family, the gens Smaragd (the family of Aynard), and might have been the last of such churches in Hungary. The church was a three-nave basilica; the cloister was attached to one of the sides.
In 1398, the Aynards went out of favor and the king ordered their property to be confiscated. Zsámbék was transferred to the Maróthi family, and in 1477, when these became extinct, Matthias Corvinus transferred the monastery to the Pauline Fathers. The church and the monastery were subsequently rebuilt in the Gothic style.
The monastery was badly damaged during Turkish rule in Hungary. In the 17th century, the church became property of the Zichy family which used a chapel in the monastery for services instead. On June 28, 1736, the church collapsed as a result of an earthquake, and since then has been deserted.
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.
