Galgberget is a nature reserve just north of Visby on Gotland, Sweden. The area is bounded to the west by the cliff edge, in the east by County Road 149, and in the south by the town of Visby.
Galgberget is named after the still remaining gallows, built during the 13th century, where local criminals used to be executed. It was claimed to be the only preserved Medieval execution site in Europe however there is another one near Furtner Teich, Austria. The gallows consist of a low, circular stone wall with three pillars of stone rising from it.
