The Roman Catholic parish church of Bük, a small late-Gothic structure with eighteenth-century Baroque overlays. The interior is plain but quietly handsome — wooden pews, a painted ceiling, and an altar dedicated to Saint Kelemen (Clement). The churchyard contains a number of older tombstones, including those of the Felsőbüki Nagy family.
Worth a five-minute look if you are walking around the old village centre. Generally open before and after Sunday Mass; otherwise the door is usually locked.
