The narrow choir has a flat ceiling with exposed beams. The apse has a traditional design, with a semicircular ground plan and a half cupola. Use of the apse as a choir termination is a feature from Middle Ages church architecture. In the apse there are five, small, stained glass windows. The windows depict from left to right: Christ before he was crucified on the hill Golgotha, the Crucifixion of Christ and Christ after the Resurrection.
