Heilige Aldegundis

Neo-Gothic church with a tower from the 14th century.

The St. Martinus Church from 1909 because of, among other things, a Renaissance communion bench, a late Gothic Marianum and a crucifix from 1539. This church is listed as a National Monument of the Netherlands.

The current Roman Catholic St. Martin's Church was built in 1936-1937 to a design by architect Stefan Dings. The church replaced an older water board church from 1838, which in turn replaced an old Romanesque church. Initially, there were other plans in 1930, and Dings would not become the architect of the new church. In the early 1930s, it was realized that the water board church from 1838 needed to be replaced. The local architect Reijnders made a design for a new church. It would be a round domed church with a high bell tower next to it. This design looked a bit like the St. Egbertus Church in Almelo) . The pastor was happy with the design. Unfortunately, the pastor passed away. And his successor did not agree with Reijnders' design at all. The new pastor again chose Stefan Dings as architect and had him make a new design. And that became the new church of Horn. Reijnders' actual design drawings were on display at the exhibition of the Horn Local History Association in September 2008.
