About one hundred years ago, you could probably see this at the cache location.
Fjellseter Sanatorium, a beautiful building, built in swiss style. It was opened in 1899. The sanatorium was popular and well known in Norway and abroad. The main building was destroyed by fire in 1917, but the annex was still standing and was used as hotel and restaurant after the fire. All buildings are now gone and replaced by a public space to park cars.
Today you can also find a chapel and a sport society cabin in the area.
