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:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
