The field of Balloo is 367 acre heather field located between the villages; Gasteren, Rolde and Loon.
The heather field lies on an elevated plateau between the valleys of Looner Diep and Rolderdiep. The mostly heather and grassy areas are interpersed by bog lakes, a bit of pinewood and small sand dunes. The field has old sandroads and chariot tracks dated back from the middle ages.
Archeologist have found gravehills, urnfields and signs of agriculture from the iron age. And findings which suggest poeple lived there in the stone age.
