The church has one nave and the altar space is situated at the height of the floor. There is a wooden statue of the resurrected Christ and a cross on the altar. The whole building is dominated by the exact symmetry - two pulpits, two rows of pews - men sat on the left, women on the right side. More than 900 people can be seated on the ground floor and on the organ gallery. There is an organ from 1894 on the gallery.
In 1909, the Mausoleum of Imre Thököly (1657 – 1705) was built to the church. Thököly came from Kežmarok and was the leading personality of the anti-Habsburg uprising organized by the Hungarian nobility. He was also the fighter for religious freedom. After defeat, he took refuge in the Town of Izmid in Turkey where he also died. In 1906, his remains were taken to Kežmarok. In Mausoleum, there is a sarcophagus with Thököly´s remains, the original gravestone from Izmid, and a new gravestone with the relief Thököly, which is Barnabáš Holló´s work.
