Thingbæk Lime Mines is a now closed mining area under Rold Skov in North Jutland not far from the villages of Rebild, Gravlev and Experience. The mines, which are part of the Rebild Center, were acquired by sculptor Anders Bundgaard in 1905. In 1926, his son Christian Bundgaard started an actual lime mining operation in Thingbæk.

Thingbæk Lime Mines is a now closed mining area under Rold Skov in North Jutland not far from the villages of Rebild, Gravlev and Experience. The mines, which are part of the Rebild Center, were acquired by sculptor Anders Bundgaard in 1905. In 1926, his son Christian Bundgaard started an actual lime mining operation in Thingbæk. Mining ceased, however, due to lack of profitability in the late 1940s / early 1950s. It has been open to visitors since 1935 and also houses the Bundgaards Museum. Here, Anders Bundgaard set up a number of plaster models in the hallways, among other things. In addition, a number of works by his colleague Carl Johan Bonnesen are also exhibited. Lime mines are typical locations for bats in winter. In Thingbæk there is five different species and when they go to sleep, can one sees them hiding in cracks and crevices in the lime. They arrive in the mines in October-November and leave the mines again in March-April. The bats are counted every winter, and their number is 500 - 900 pcs. The vast majority of bats wintering in Thingbæk are Waterflagmus (Myotis daubentonii). In addition, some ladybird mice (Myotis dasycneme), Fritish flag mouse (Myotis night egg) and Brandt bat (Myotis brandti) occur. Long-eared bats (Plecotus auritus) appear only in single specimens in the pit and only in the middle of winter.
