Jislum is a village in Noardeast-Fryslân in the province of Friesland, the Netherlands. It had a population of around 65 in January 2017.[3] Before 2019, the village was part of the Ferwerderadiel municipality.
There is a restored windmill in the village called De Volharding.
The village was first mentioned in 944 as Gisleheim and means "settlement of the people of Gisilo".[4] In 1840, Jislum was home to 118 people. The Dutch Reformed church dates from 1886 and is a replacement of a medieval church.[5] The polder mill De Volharding was built in 1872. It was in service until 1955. In 1994, it was restored and since 2006, it performs as a backup to the pumping station.[6]
