The village was first mentioned in 1426 with the name Żeliszew. From the 16th to the 18th centuries, the town was the property of various noble families: the Oborskis, Głogów Rudzińskis, and the Cieszkowskis. In 1533 the Oborskis granted the privilege to set up a private town here. They erected it as a parish. Initially, the city functioned under the names Żeliszew and Łukowiec. Because the town was located just a few kilometers away from four other cities - Latowicz, Kuflew, Seroczyn and Wodynie - the economy never developed. In the 18th century, the city had a population of just 150. The situation didn't improve when the town's name was changed to Jeruzalem , the name which eventually evolved into today's form. During the Counter-Reformation and the Swedish Deluge the town was a local pilgrimage center. In 1810, Jerusalem still only had 198 residents and around 1820 the town finally lost its charter. On March 23, 1948, a branch of the National Armed Forces led by Zygmunt Jezierski performed an action against the local Milicja Obywatelskapolice station.
With the founding of the parish in the 16th century, the first wooden church of St. Wojciech of Jeruzalu was built, but was later destroyed. In its place, a new church was built from 1757 to 1758, which, with small changes in the process of remodeling in the 19th century, has survived to this day. The church is wooden, deployed on a cruciform plan with an added vestry. It has a gable roof, covered with shingles. Between the nave and the chancel is a characteristic of this type of construction - a rainbow arch and on it a crucifix and statues of the Virgin Mary and St. John from the 16th century. The interior is richly decorated in baroque style with medieval elements. The church is the seat of the St. Wojciech parish, which belongs to the Siennicki deanery, which is part of the Diocese of Warsaw-Praga.
