Church of the Assumption of Our Lady in Grunta, Romanesque Revival church in Grunta, Czech Republic.

The Church of the Assumption of Our Lady in Grunta is a massive Neo-Romanesque three-nave basilica with two western towers, built in 1905–1908 to a plan by architect Rudolf Vomáčka and executed by builder Jan Sklenář. It stands oriented in the middle of the cemetery on the southern edge of the village, surrounded by a wall with Neo-Gothic battlements and a Neo-Romanesque mortuary. Its interior holds Secessionist-influenced paintings by František Urban and his wife, and the furnishings are likewise Secessionist-Neo-Romanesque.

A church existed here by 1305; miners from Kutná Hora rebuilt it between 1367 and 1398. After demolition in 1814, a simple nave was completed in 1817, and the present church was built in 1905–1908 to plans by Rudolf Vomáčka, executed by builder Jan Sklenář. It was listed as a cultural monument in 1987.

The church is a filiální (branch) church of the Kutná Hora arcidecanate since the local parish was dissolved in 2007. Its furnishings are entirely in the Secessionist-Neo-Romanesque style, and the interior paintings were made by painter František Urban and his wife.

The church stands in the middle of the cemetery on the southern edge of Grunta, oriented like its predecessors; the cemetery is enclosed by a wall with neo-Gothic battlements and a neo-Romanesque mortuary in its southern part. The building was fully restored in 2024, so the exterior can be seen in renewed condition.

Three Renaissance tombstones of the Libenický z Vrchovišť family and a Gothic bell with the inscription "ave maria gratia + pane bozie dai swobodu tiem kdoz te milugi a twau prawdu wyznawagi" survive from the earlier church. Local lore wrongly credits the violinist Jan Kubelík with funding the 1905–1908 building; the 225,000 crowns came from the church's own endowment, and Antonín Zápotocký worked on the site as a stonemason's apprentice.
