The Stachelberg fortress is located just northwest of Babí, between Trutnov and Žacléř.
The Stachelberg fortress was built as protection for Labavské sedlo (Saddleback), which is the land gate between the Krkonoše and Vraní hory.
The museum in Stachelberg has been opened since 1993 and the owners expand the accessible parts of the fortress every year.
However, the owner changed in 2005 and presently it is owned by the Stachelberg Civic Association, a group of enthusiasts, who consider their job a hobby and do it voluntarily.
It is worth mentioning that the fortress is financed only by the visitors’ entrance fee and occasionally by donors who are willing to help.
