Reformed church, Reformed Christianity church in Karcsa, Hungary.

The Reformed church in Karcsa stands on a small rise by the Karcsa stream, built of carefully carved red trachyte blocks and covered with shingles. Its short, nearly square nave is much wider than the sanctuary, which was originally a separate brick rotunda. The plain southern door contrasts with the western portal, where lions support the consoles beneath a six-column gable, and five semicircular niches survive in the former sanctuary.

A brick rotunda already stood here in the 12th century. The Johannite knights who held the area began a larger, two-towered church beside it, but work stopped when the village passed to Tamás, son of Baksa, in 1282, and the church remained towerless. Protestants took it over in 1527; by the early 18th century only bare walls stood, and it was restored in 1767, 1896 and 1964–1969.

The church has belonged to the Protestant congregation since 1527, and the Reformed community of Karcsa still uses it. Music events are held in the building regularly. The poet Mihály Tompa wrote a poem about the church, and a local legend says frightened fairies dropped the bell meant for the tower, which is why the tower was never finished.

The church is located in the village center of Karcsa and is easily reached on foot, especially if you are hiking the Alföldi Blue Trail nearby. Visitors should dress respectfully and be mindful of services, as the church remains an active place of worship.

The round sanctuary was built of brick, not stone, and still shows five semicircular niches inside. A local legend says fairies, frightened by witches, dropped the bell they were carrying into the tower, and the finished tower collapsed with it.
