The church was built in 1576 as a late Gothic structure inside the cemetery founded in 1549 on the left bank of the Otava in Pražské Předměstí. The cemetery closed in 1950, was cleared in 1973 to create a memorial park, and the church reopened to the public in 1977. Floods in 2002 badly damaged its interior furnishings.

The church is a frequent venue for exhibitions, concerts and festive social events. Inside stands a Renaissance pulpit; the interior decoration and furnishings were badly damaged in the catastrophic floods of 2002. The cemetery around it, closed in 1950, now serves as a symbolic memorial park with preserved tombstones of notable figures.

The church stands inside the former cemetery grounds in Písek's Pražské Předměstí, near the streets Na Výstavišti and Svatotrojická, with the winter stadium just to the west. The grounds were opened to the public as a memorial park in 1977. Enter by the main door, where the graves of French officers lie to the left.

The three-manual organ, opus 3340 built by Rieger-Kloss in 1966, came from the estate of traveller Jiří Hanzelka. In 2018 a return of the original altars to the organ's place was considered, with the instrument possibly moving to a concert hall.
