Sanatorium on Voksenkollen

Built in 1897, with the backing of the Ringnes brothers, outside the then boundaries of Christiania and run by a pioneer of Norwegian healthcare, Dr I. C. Holm. Grieg stayed here periodically.

Spending an increasing amount of time in Christiania during the last years of his life, Grieg planned to sell Troldhaugen and move permanently to the capital (in the Slemdal area), but those plans came to nought.
