Mandø Church is a simple whitewashed building dating from 1639, built on the island's highest dune point and visible from across the tidal flats. It was restored in 1727 and has remained largely unchanged since. The four-nave structure uses large medieval bricks and has the practical plainness typical of Danish rural churches built during the Reformation era.
The church stands at the geographical and historical heart of the island community. The graveyard around it contains headstones that tell the story of a maritime society: sea captains, fishermen, and the women who ran the farms while the men were away. Many of the stones record deaths at sea.
The church is generally open to visitors during summer months. Even if it is closed, the exterior and graveyard are worth the short walk from the main road through the village.
