Hakastein Church was a church under Gimsøy Abbey near Skien in Norway. It is first referred to in a manuscript from 1354.[1]
In 2001, archaeologists uncovered post-holes and other features which are believed to belong to the church. Radiocarbon dating of material from the post-holes suggest that the church was constructed between 1010 and 1040, making it one of Norway's earliest post churches. Earlier features on the site, such as graves, were dated to the mid 10th century.[2]
