The Dutch Reformed Church on the main square is the oldest building in Den Burg, with foundations and Romanesque elements going back to the eleventh century and a Gothic brick tower added in the fifteenth. After a lightning strike in 1537 the nave was enlarged into the three-aisle basilica that stands today.
The interior is whitewashed and bare in the Protestant manner — the Reformation came thoroughly to Texel — with a wooden barrel vault and a baroque pulpit. Memorial slabs and ship-shaped offerings hung from the rafters recall the island's long maritime history. Open weekday afternoons in season and during Sunday services; the tower can sometimes be climbed for a view across the village rooftops and out over the polders.
