Góra Kalwaria (; "Calvary Mountain", , Ger) is a town on the Vistula River in the Masovian Voivodeship, in east-central Poland. It is situated approximately southeast of Warsaw and has a population of around 12,109 (as of 2019). The town has strong religious significance for both Catholic Christians and Hasidic Jews of the Ger dynasty. History The village of Góra already existed in the 13th century. It was a private village of Polish nobility, administratively located in the Czersk County in the Masovian Voivodeship in the Greater Poland Province of the Polish Crown. Completely destroyed during a Swedish occupation known as the Deluge, in 1666, it became the property of Stefan Wierzbowski, Bishop of Poznań, who decided to found a new town on the ruins. His plan was to build a calvary — a religious center dedicated to passion plays and services, which was popular in the early modern Poland. He was encouraged by the fact that the local landscape resembled that of the Holy Land. In 1670, the town was renamed Nowa Jerozolima, granted city rights and construction work kicked off. The urban design was based on medieval maps of Jerusalem, and the street grid formed a Latin cross. The bishop invited Dominican, Bernardine and Piarist orders to settle in the town, which soon became dotted with monasteries, churches, chapels and passion paths (such as stations of the Cross). The town was supposed to be a purely Christian one and Jews were not allowed to settle there. After Bishop Wierzbowski's death the decline of the town began. Many churches and chapels were pulled down, and in the years 1883–1919 the town was deprived of city rights. In the early 19th century, the ban on Jewish settlement was lifted and afterwards Jews became the predominant group in the town, also due to their expulsion from Russia (see Pale of Settlement). Góra Kalwaria then became one of the major centers of Hasidic Judaism and home to the Ger dynasty. During World War I, Góra Kalwaria was occupied by Germany. On November 11, 1918, the day Poland regained independence, local Polish firefighters led by Szymon Adamiec disarmed the German troops without a fight and liberated the town. In 1919, during the Polish–Soviet War, several Polish horse artillery squadrons were formed in the town. On August 13–14, 1920, Poles successfully defended the town from the invading Russians.
