Østhagan Landskapvernområde, Grua gruvedistrikt, Lunner, Akershus, Norge
The Østhagan Nature Reserve is located due east of the village of Grua. It comprises some old iron mines, limestone quarries, and limestone furnaces in an area of ca. 30.000m2.
This is one of the main attractions in the Grua district. In a fenced-in area of 0.03 km2 you will find two limestone ovens, several limestone quarries, and some very old iron mines. In addition, the geology of Østhagan is very visible in many places thanks to the exploitation of limestone. The iron mines at Østhagan were already operated in the early 16th century, which makes them among the oldest in Norway. Just before entering the Østhagan area, you will see the opening of one of the mines at the left side of the road. A couple of years ago the mine was emptied of water, and many interesting old things were found. In the fenced-in area there are three more iron mines. The limestone quarries are much younger. The exploitation of limestone was started in 1910 and continued intermittently till 1937. The limestone was burned in the two limestone ovens. The restoration of the ovens will be continued in the near future, but already now it is possible to get a good impression of how these ovens worked. The burnt limestone was used for cement. The mines are protected as historical/geological sites; collecting is illegal.
Due to its fertile soil, the area is also known for its rich flora.
