Saint Anne church in Piaseczno, Gothic church in Piaseczno, Poland

Saint Anne in Piaseczno is a brick church featuring Gothic architectural elements with a prominent bell tower near the town center. The building displays traditional church proportions with a main nave and side structures typical of this architectural style.

The church was built in 1565 in late Gothic style with Renaissance elements, replacing a wooden church from around 1350. After damage in the Polish-Swedish wars, Józef Aleksander Sułkowski funded a restoration in 1736, when the interior was rebuilt to Karol Fryderyk Pöppelmann's Baroque design. Artillery damaged it in 1914, and it was regothicised outside in 1958–1960.

The church is dedicated to Saint Anne, though it was first consecrated under the invocation of All Saints; the earlier wooden church on the site, from around 1350, was dedicated to Saint Matthias and Saint Anne. A late-Baroque statue of Saint John of Nepomucen stands at the top of the east facade, placed there during the 1736 restoration.

The church is centrally located in Piaseczno and easily accessible on foot from the town center. Visitors can view the building outside of service times, though it is respectful to avoid entering during active religious ceremonies.

The church was damaged by artillery shells in 1914 during World War I. A statue of Saint John Nepomucene in late Baroque style stands atop the eastern facade, placed there during the 1736 restoration. The side chapel of the Holy Cross was added in 1960 to a design by architect Lech Dunin.
