Church of Saint John the Baptist, Gothic church in Dvůr Králové nad Labem, Czech Republic

The Church of Saint John the Baptist is a Gothic church with an irregular ground plan, oriented east, built between 1399 and 1400 on the site of a 13th-century Romanesque basilica. Its three naves are separated by two pairs of columns on polygonal pedestals, and the tower, raised to 64 metres in 1894, has a flat for a tower keeper and three bells: Saint John, Passing bell and Meridian bell.

A 13th-century Romanesque single-nave basilica first stood on the site; a Gothic church replaced it in 1345, and the present three-nave church was built in 1399–1400 for Queen Sophia of Bavaria. After a 15th-century fire it was rebuilt with a vestibule and tower, and in 1893–1900 František Schmoranz's regothicisation raised the tower to 64 metres.

The church gained attention in 1817 when Václav Hanka found a manuscript in its tower dungeon, later determined to be a forgery yet influential in Czech literature.

The church stands in the town centre, with the main entrance on the south side through the wooden door of the vestibule; a separate portal leads into the tower. The north side has no windows because of the former town fortifications, so the interior light comes from the south and east. The tower reaches 64 metres.

A manuscript found in the tower chamber in 1817 caused a stir in the Czech literary world, though it was later revealed to be a forgery. This discovery showed how much historical finds could influence national identity and cultural thinking at the time.
