The Church of the Blessed Sacrament in Słomniki, built between 1888 and 1893, was erected on the site of a former temple that was dismantled in 1890. The history of the church dates back to 1335, when King Casimir the Great founded the first wooden church dedicated to St. Michael the Archangel, which stood until 1648. Subsequently, a new building was constructed and consecrated by Bishop Mikołaj Oborski. In the 18th century, when the temple was on the verge of ruin, Archbishop Michał Jerzy Poniatowski agreed to the sale of church silver to finance its renovation. The current structure, designed in the Neo-Gothic style, features a richly decorated interior. In the chancel, separated by a stone balustrade, stands the main altar with a crucifix and statues of Saints Augustine and Ambrose. A valuable work of art is the 15th-century chasuble kept in the sacristy, depicting scenes related to the Infant Jesus. The side aisles house altars, including one dedicated to the Virgin Mary with an 18th-century Baroque robe and an altar of Jesus the Merciful. A particularly interesting feature is the chapel with the image of Our Lady of Perpetual Help. The church plays an important cultural and religious role for the local community, and funeral processions are conducted to the parish cemetery on Poniatowski Street.
