Château de Lavardens dominates the skyline of surrounding lands. Originally built in the 12th century, it was later a residence of Counts of Armagnac. The present massive structure dates from 1620 onwards and it was built on the ruins of medieval castle (destroyed by King's soldiers in 1496).
The first written record of church in Danmark locality date back to the year 1291. Close to the church are several stones with a Christian text and cross inscribed. The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
