Drolsum

Drolsum is a rural area west of Tyrifjorden lake in Modum, stretching from the Henåa river toward Vikersund. The region features dense forests and farmland that shape its landscape.

The earliest mention of Drolsum appears in a document from 1456 describing property transactions in the southern Drolshamar region. This record shows the area has been inhabited and used for centuries.

Rud Church shapes the village with its timber structure and serves as a gathering place for the local community. The building carries visible marks of its past, including damage from a fire that left traces on its walls.

The area is accessible via Riksvei 350 road and Drolsum station on the Randsfjord railway line. These transport connections provide good access for visitors and residents.

Ole Witloch from this area discovered cobalt deposits that led to the establishment of the Royal Blue Factory. This discovery shaped the country's industrial development.
