The Church of Sant Jaume stands at the centre of Alcudia's old town, a solid Gothic structure built over several centuries beginning in the 14th century. The current building is largely the result of a 19th-century restoration that reinforced and extended the medieval fabric — the tower is the most clearly Gothic element, visible from most of the town. Inside, the single nave is broad and austere, with chapels along the sides.
The church is the focus of the Festes de Sant Jaume in the last week of July, when the town holds its major annual celebrations with processions, music, and the ritual of the cavallets — small horse figures carried through the streets in a tradition that dates back centuries. If you are in the area in late July, it is worth arranging your visit to coincide with the festival.
The church is open to visitors during the day outside of service times. It doesn't require a long visit, but the stone square in front of it is pleasant in the evening, and several of the best cafes in the old town are within a short walk.
