The village was probably first mentioned in the 12th century as Grunlo, and means "green open forest". Grolloo is an
esdorp which developed in the Early Middle Ages on the
Hondsrug as a satellite of
Rolde. The village has two
essen (communal pastures) on the east-side and a little
brink (village square). From 1550 until 1669, the
Landdag (legislative assembly) of the province of
Drenthe was held in Grollerholt, a forest near Grollo. The village used to have communal land. The transition to private priority started late in 1859. The Dutch blues band
Cuby + Blizzards was founded in Grolloo. There is a museum in the small farm house where they began. Grolloo has a statue of
Harry Muskee, one of the band's founders and lead singer. == Gallery ==
