Weilburg Railway Tunnel

The Weilburg railway tunnel is 302 meters long and runs parallel to the well-known shipping tunnel. It thus pierces the Mühlberg, which meant that the railway line did not have to follow the Lahn loop in Weilburg. The railway tunnel was built by Italian tunnel construction specialists as part of the construction of the Lahn Valley Railway from Lahnstein to Wetzlar in 1862 under the direction of Moritz Hilf (1819 to 1884). Its tunnel portals, designed in the neo-Romantic and neo-Gothic style, are striking and were designed by the building architect Heinrich Velde (1827 to 1905), who was born in Diez an der Lahn. The north portal had a castle-like double tower facade, the south portal has stepped gables.
There is a tunnel house to the east of the northern tunnel portal.
