Saint Peter of Alcantara Church in Karviná-Doly, Baroque church in Karviná-Doly, Czech Republic

Saint Peter of Alcantara Church is a single-nave hall church built in the late Baroque style between 1756 and 1759, with a tower topped by a pyramidal roof and clock faces. Its main altar holds a painting of the titular saint repainted in 1924, and a Gothic stone baptismal font from the older church stands in a corner.

The present church was built between 1756 and 1759 by Jan František Larisch in the late Baroque style, replacing an earlier wooden church dedicated to Saint Martin first mentioned in 1447. It was consecrated in 1759 by Wrocław bishop Filip Gothard Schaffgotsch, and a family tomb was placed inside. During construction the masonry vaults were taken down and replaced with wooden ones.

The church is known as the Šikmý kostel (Leaning Church), the title of Karin Lednická's 2020 novel and its 2021 and 2024 sequels, set around it. Two bronze bells cast by Josef Kadlec of Hrozenkov were consecrated on 8 December 2012; the larger, 157 kg bell honours Saint Henry in memory of the demolished church at Solec.

The church stands in Karviná-Doly, the mining quarter, and its tilted silhouette is visible from the surrounding streets; the tower clock face is lit. The building is a protected cultural monument and a working parish church, so visits depend on services. Restoration of the roof, façade and adjacent tomb began in 2026 and should end in 2027.

The church has tilted about 7 degrees toward the south because of coal mining beneath it, with the ground having sunk about 37 meters from its original height. Despite this dramatic shift, the building remains standing and continues to serve its community.
