Quick Gräsbo history. Below, the schools history.

By the former shoreline, north of Gräsbo you can find the remains of a Stone Age dwelling site. Rock carvings are visible west of the old village site. The little river east of Gräsbo was possible to navigate during the Iron Age, all the way down to Huddunge. By the river at Nordsjö, today an overgrown lake you can find remains of a Harbor and a number of Iron Age burial mounds.

Gräsbo is an old village. The name is probably derived from Gräs (grass) and bo (dwelling, farm). Named after the waste grass lands by the river. Not suitable for anything else than cattle.

Cattle farming was important economic activity for the village, proven by old tax and army records. The army records show that the village exported meat to the Swedish Army when it fought down in Europe and in addition also exported large amounts of hops for beer. In the old days it was mandatory for all Swedish farms to have 20 rods ( strings) of hops. In Gräsbo the farms had more than 5000 rods each. Enormous amounts of beer from Gräsbo.

In the old Swedish document archives, you find a first reference from the 13-century. At that time there where two farms and one seat farm for the aristocracy. In one of the oldest still existing law codex's (Upplandslagen) Gräsbo is mentioned as a "hamna". A hamna is a remain of the old viking age army structure (ledung). The fact that Gräsbo is mentioned as a hamna indicates a pre historic context. Next reference of Gräsbo is in a will from mid 1300's.

It's told by the village old that before the village was moved 150 years ago, the farm buildings where so close that you could jump between the houses. Old Gräsbo village site was where the power lines crosses the road to Huddunge. All that remains is a hops garden east of the road.
