Frognerseteren means the seter (“mountain dairy farm”, roughly comparable to shieling) of Frogner (Manor). Frognerseteren with parts of the Nordmarka forest (Frognerseterskogen) was part of Frogner Manor until 1848, when the owner Jacob Benjamin Wegner sold the rest of the estate but kept Frognerseteren.

Wegner’s heirs sold Frognerseteren to Thomas Johannessen Heftye in 1864, and Heftye’s heirs sold Frognerseteren to Christiania municipality in 1889.
