Overview
Overview
Wegner had a grand oval driveway built in front of the main building with a sundial in the middle of the lawn. The sundial is constructed as an open globe, where the meridians cast a shadow on sunny days onto the inner part of the globe, hitting the inside of the equator line and thus showing the time, specifically the astronomical solar time. Odd Gunnar Skagestad wrote in 2020 that the nearly 200-year-old sundial is greatly neglected and called for efforts to preserve it. It is one of two sundials in Frogner Park, alongside Gustav Vigeland's sundial from ca. The nearby Henriette Wegner Pavilion commemorates his wife and their 1824 wedding in her native Hamburg.
