In 1186, a monastery was founded near Pingjum: Vinea Domini. The monks worked very hard, they lived sobely and wore white robes. In those days, monasteries owned a lot of (fertile) land. Hence, they were powerful and had in important part in the development of Friesland.
In the 12th century, Pingjum was protected by a surrounding dyke: ‘De Halsban‘. This medieval dyke is symbolically reflected by the yellow rim in the coat of arms of Pingjum.
There are indications that a church was built in 1270.
A civil war broke out in Friesland at the beginning of the 14th century. This war was interrupted in 1345 by an invasion from Holland, which was led by the count of Holland: William IV. His armada was well prepared and landed near Stavoren. The Frisian peasant army won the battle. Van Lenneps Seerp van Adeelen (one of the leaders of the Frisian army, who lived in Pingjum) and William IV were killed in action. The civil war continued after the ‘Battle of Warns‘ until 1498 and was waged by ‘Schieringers’ against ‘Vetkopers’. Pingjum was also affected by this war.
