The Church of St. Mary on the Sand (, ) is a Catholic church in Wrocław, in Silesia, located on a small island in the Oder River, in the heart of the city. Founded in the 12th century, it is one of the oldest Gothic churches in the country. History At the end of the eleventh century the descendants of Count Palatine and the great Polish nobleman Piotr Włostowic allowed the construction of a Romanesque church on this small island, hence its name on the Sand. This powerful family was involved in the evangelization of Silesia. It is dedicated to the Virgin Mary, patron saint of the governor's wife (statthalter), Maria Włast. The tympanum above the entrance portal shows a statue of the Virgin and Child with a small statue of the kneeling foundress, Maria Włast, holding her son in her arms next to it. Gothic church The Romanesque church was demolished in the 14th century to make way for a larger Gothic church, built in brick between 1334 and 1430 according to the plans of the architect Master Peschel. It was supposed to have two towers, but the north tower was never completed. The nave, lit by huge windows, is 78 meters long. The Gothic vaults rise to 24 meters high. Additional work took place in the following centuries, including the construction of the Chapel of the Holy Cross by Antonio Coldin in 1666. It is the oldest baroque construction in the city. The church was sacked by Swedish troops in 1632 during the Thirty Years' War. A century later, lightning struck the south tower destroying its roof, while a few days earlier the new 4.7 ton bell had just been blessed. During the Seven Years' War, the Prussians used the church as an ammunition depot. Second World War Hitler made Breslau a fortified city in 1944. When the Soviet troops advanced to the west in 1945, the Sandkirche and the buildings served as headquarters for the German army, which was conscious of fighting a dead-end battle. General Hermann von Niehoff commanded the 371st Infantry Division. During the fighting, most of Breslau's historical monuments were destroyed or severely damaged. The Sandkirche also burned down. The baroque interior disappeared completely, the paintings of Michael Willmann, the baroque pulpit by Franz Joseph Mangoldt, the organ are destroyed by the flames. The German population was expelled after the war and replaced by
