Battery Oldenburg

Calais, France

Battery Oldenburg is a German artillery battery, built during World War II as part of the Atlantic Wall, and situated east of Calais. The battery began in 1940 with artillery guns in an open emplacement. The Organisation Todt built casemates around two 240mm guns during the war.

Both casemates or Turms (towers) are 35 meters long and 15 meters high, positioned in a slight offset from each other to gain a broader range with both guns. Turm East and Turm West housed guns of Russian origin that were captured by the German army during World War I and re-chambered by Krupp from 255mm to 240mm.

Both casemates are 35 meters long and 15 meters high above ground level. The western of the two casemates, Turm West is two storeys deep, while the eastern casemate, Turm East, is three storeys deep.

Besides the two casemates, battery Oldenburg has a combined fire control and hospital bunker, which still has a beautiful fresco and other paintings, ammunition bunkers and personnel bunkers. Behind the two casemates and fire control bunker is the barrack site used by Organisation Todt.

Battery Oldenburg surrendered to Canadian forces in 1944.

Easy free off road parking for at least 12 cars. Easy 5 minute walk to fort on wooden walkway.

Well preserved German defences and pleasant walk. The scale of the defences is impressive and makes you wonder how many French workers died building them under the German occupying forces.

Trencín Castle

Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.

History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.

Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.

Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
