1576: Ecke Claessen 1587: Hidde Onsta Verhildersum is a borg directly to the east of the town of Leens in the Dutch province of Groningen.

In a document mention is made of the reconstruction of the borg after 1514 for the sum of 1200 gold pieces, excluding some exterior buildings.

Complaints by him are made with regard to troubles caused by billeted soldiers with their two wives and a child, who reside at the borg due to the Eighty Years' War.

During the war Eylco Onsta flees to East Frisia, but despite this keeps calling himself hoofdeling of Wetsinge, Sauwerd and Verhildersum.

The schathuis used to be a farmhouse and derives its name from the old Frysian word skat, which means cattle.

From 1994 to 2012, the fine dining restaurant Schathoes Verhildersum of chef Dick Soek was housed in the building.
