Already in Roman times the road between Augusta Raurica and Vindonissa led over the Bözberg, although it was further north than the present-day route, from Effingen via Remigen to Stilli.

The village is first recorded in 1064 as part of the domain of Rein, which belonged to the Benedictine monastery of Murbach in Alsace.

In 1291 the domain of Rein was purchased by King Rudolf I of Habsburg, who was thus the most significant landowner in the area as well as the most senior judge.

In 1345 Queen Agnes of Hungary gifted the domain to the convent of the Poor Clares in Wittichen in the Black Forest.

In 1460 the city of Bern conquered the district west of the Aare river, but made no change to the rights of the convent.

In 1566 the jurisdiction of the court at Bözberg was subdivided, and from then on the domain's legal cases were heard at the neighbouring village of Stilli.

In March 1798 the French conquered Switzerland, took away the powers of the merciful Lords of Bern, and proclaimed the Helvetic Republic.

In 1799 the front line of the Napoleonic Wars ran through the middle of the lower Aar valley, and there were several French Army encampments in the area.

The inhabitants of the local villages suffered great penury due to the army's requisitioning and plundering.

It lies about 2 miles (3.2 km) NNW of Brugg, at a transition point between two areas of the Jura, in the North-west corner of the plain of Rüfenach.

However the parish only extends as far as the steep southern slope: the extensive neighbouring 2,000 ft (610 m) high plateau belongs to Villigen.

54.8% of the total land area is heavily forested and 1.7% is covered with orchards or small clusters of trees.
