The interior of the Calvinist church, on a small hill just north of Báthory István utca, is refreshingly plain and its long lancet windows, which flood the nave with light, accentuate the church’s masterpiece – the ribbed vaulted ceiling. István Báthory’s remains lie in a marble tomb at the back of the church; the family’s coat of arms embellished with wyverns (dragonlike creatures) is on top of the tomb. The 17th-century wooden bell tower, standing apart from the church (as was once required of Calvinists in this Catholic country), has a Gothic roof with four little turrets.
