The Franciscan Church in Drohiczyn, dedicated to the Assumption of the Blessed Virgin Mary, boasts a rich history dating back to the 15th century, when Mikołaj Nassuta, the starost of Drohiczyn, founded the Franciscan convent. Construction of the brick Baroque church began around 1682, funded by the local nobility, and was completed around 1715; its consecration took place in 1733. The church's interior features Rococo altars and a unique Loretto House. Between 1773 and 1777, a bell tower was added, and the entire monastic complex was built in the Baroque style according to the design of Father Kazimierz Kamieński. The church has endured numerous historical upheavals, including destruction during World War II, as well as fires and devastation during the partitions, when the Franciscans were expelled and the church was converted into an Orthodox church. After World War II, the church was rebuilt, and renovations continued into the 1990s, restoring it to its former glory. Interestingly, the site has witnessed many tragedies, including the murder of nuns during the Swedish Deluge. Today, the church serves as the home of the Diocesan Museum, the House for Retired Priests, and Caritas, underscoring its cultural and religious significance in the region.
