The Seething Observatory sits on a 2 acre site at the edge of Seething Airfield in South Norfolk. Based just 8 miles south of Norwich in the middle of the countryside, visitors and members can enjoy stunning dark, star filled skies. See our site page for full details.

Society activities centre around the Clubhouse building. Built back in 1994 when the Observatory moved to Seething, this building is an ideal place for members to share experiences and to chat in a warm, friendly environment. See the clubhouse page.
