During the February flood of 1825, Frisian seawalls broke. Pingjum was spared thanks to a dike around the village known as the Pingjumer Golden Collar (Pingjumer Gulden Halsband). In 1892 the province of Friesland decided to put an end to the Pingjumer Golden Collar coastal protection, although in several places the dike is still visible. This ring dyke was originally built in part to reclaim land from the Marne Estuary to the north of the village.
