Loos Double Crassier

These two slag heaps are a major terrain feature, and were the scene of heavy fighting during the Battle of Loos (1915). They stand nearby where the main Pit Head stood within the town of Loos. The large double tower with connecting gantry was christened "Tower Bridge" by British troops approaching Loos in trenches to the West. The pit head was destroyed during the battle, and was not rebuilt.
