Saint Lawrence church and capucine monastery in Zakroczym, Baroque church and monastery in Zakroczym, Poland

Saint Lawrence church is a Baroque building with twin bell towers and stone walls decorated with religious ornaments on its exterior. The adjoining Capucine monastery forms a unified complex with the church, reflecting the religious and architectural character of the site.

The monastery complex was built between 1757 and 1765. It was destroyed during the Napoleonic Wars and again during the siege of Modlin Fortress in the November Uprising; from 11 to 20 September 1831 the insurgent government and Sejm met in its refectory, as a plaque recalls. Russian authorities dissolved the monastery on 8 June 1892, and the Capuchins regained it on 31 July 1932.

The monastery holds a small museum of sacred art. From 1968 to 1997 Father Benignus Sosnowski ran a temperance ministry here, first as a retreat house for sobriety pastoral care and now as the Ośrodek Apostolstwa Trzeźwości. A plaque in the refectory recalls the insurgent government and Sejm that met there from 11 to 20 September 1831.

The site is easily accessible, located at the intersection of national roads 62 and 7, making it convenient to reach from outside the town. Visitors should expect regular religious services and inquire about guided tour availability.

From 11 to 20 September 1831, during the November Uprising, the monastery refectory housed the insurgent government and Sejm, an event recorded on a plaque there. The room thus served as the seat of Poland's national authorities during the siege of Modlin fortress.
