Perhaps the only building of its type still standing in Tibet, Namseling Manor (Lǎngsèlín Zhuāngyuán in Chinese) is a seven-storey family mansion dating from the 17th century and recently restored with the addition of a moat and bridge. It’s a minor site with just a few murals left but it's worth a scramble around if you can find the caretaker.
The building is 3km south of the main highway near kilometre marker 161.
