Sundvollen

In the census of 1801, 71 persons lived at and nearby the farm (both farmers and serfs with their families).

As a crucial meeting point, the farm prospered from serving travelers going up to central Ringerike.

Kroksund bridge, an old stone structure at Sundvollen, was included in the Old Royal Bergen Road.

[2] Krokskogen is a forested area south of Sundvollen which forms part of Oslomarka.

The steep Krokkleiva through Krokskogen was part of King Road (Kongevei) between Sundvollen and Kleivstua.
