The Church of the Visitation of the Most Blessed Virgin Mary, otherwise known as St. Mary's Church, is a church, is one of oldest buildings in Warsaw and one of the few surviving examples of Gothic architecture in the city.
St. Mary's Church stands on the site of an ancient pagan place of worship. The church's foundation stone was laid by Janusz I the Old, Duke of Masovia and his wife, Danutė of Lithuania, in 1409. The church was consecrated in 1411. It has been modified, demolished and rebuilt several times. Originally it had one nave, was made of bricks, had a ceiling and an arch presbytery, before the end of the 15th century it was transformed into a three nave basilica.
The church's most striking characteristic is the tower, built in 1518. It is recognizable from a great distance and is depicted in the oldest images of Warsaw.
During World War II, the church was severely damaged by German forces - the roof of the nave collapsed and the upper portion of the tower was blown up. It was reconstructed in 1947-1966 to the design by Beata Trylińska.
Behind the church is small park with a set of steps that lead down to the Vistula and the so named Kościuszko banks of the river. In the square there are outdoor theatre performances and concerts which are organized locally.
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.
