The symbol of Seefeld, the ‘Little Church in the lake’, also called ‘Heiligkreuzkirche’, was built by Archduke Leopold V in 1629 and completed in 1666. The building has an unusual style for Tyrol, as it was built following the floorplan of a rotunda. The outside shows a delicate silhouette with an attractive onion tower. At that time, it was located in the middle of the artifical Kreuzsee, which was, however, drained in 1807.
