The erection of the church of St Judoc started around the middle of the 14th century. The church was built in 1380. Then or later a southern porch was added. Around 1500 the towers were made. In 1699 a refurbishment and slight renovation of the church was made, enlarging the pointed windows. In 1884, the vestry and the porch were renewed, and in 1886 the size of the windows was changed again to the original form.
The late Gothic church was erected as an orientated, aisleless building. It was built of erratic stones in the lower parts, and in the upper parts of bricks, on a rectangular plan. On the south side there is a porch, and on the west, a massive, square tower, divided into four floors with plastered friezes. In the ground floor of the tower there is another porch, to which a pointed portal with stepped jambs led. Above it there is a small round blende, and above it there are large plastered panels. The whole is topped with pinnacles and a gable roof. As in the tower, the gables of the nave and the porch received pinnacles and were decorated with blendes. The nave of the building was buttressed. The interior is covered with a flat, polychrome wooden ceiling.
