World War II

Bunker 'Ermitage Sud' was part of the Maginot Line, a series of fortifications erected by the French army along its border after the German attack during World War I.

Hardly anything remains of the Brommy Bridge over the Spree today. In 1945, the bridge was blown up by the German army to prevent the Red Army's advance.

To defend the nation against foreign attacks, a series of forts were built around Antwerp, Liège and Namur from the end of the nineteenth century. For example, the Defense Line of Antwerp consisted of sixteen larger strongholds in a wide circle around the city, including Fort Breendonk.

An eagle atop a 15-meter-high pillar was inaugurated in 1930 and originally commemorated German marines killed aboard a submarine during World War I.

The Laboe Naval Memorial's foundation stone was laid in 1927 at the mouth of the Kieler Fjord in the Baltic Sea. The 72-metre-high tower was finished in 1936.

Railway line 47, the section of the Vennbahn between Sankt Vith and Troisvierges, was commissioned in late 1889 and crossed the Our River via a brick viaduct near the German village of Hemmeres.

The Spuikom in Ostend became a military air base during the First World War. In early 1917, the German army built the Seeflugstation Flandern II to defend the port of Ostend against English attacks.
