Christian V of Denmark
Grünerløkka was named after Friedrich Grüner (1628-1674) who served as chief administrator ("Oberhauptmann") and the master of the mint ("myntmester") at Christiania from 1651 until his death in 1674. Grüner purchased the Kings Mill ("Kongens mølle") and surrounding acreage in the area from King Christian V of Denmark in 1672.
