Olterterp is a village in the municipality of Opsterland in the east of Friesland, the Netherlands. It had a population of around 75 in January 2017.[3]
The village was first mentioned in 1505 as Otterterp, and means "outer settlement".[4] The Dutch Reformed church was built in 1414 or 1415 as a replacement of an earlier church. The church was built without a tower. The tower was added in 1744.
Olterterp was home to 154 people in 1840.[5] Most of the land was owned by Ambrosius Ayso van Boelens. Around 1850, van Boelens started to cultivate the wilderness and turn it into farmland.[6]
