Not far down the road from the campsite was a museum set in and around the Block House built to assemble and launch the V2 Vengeance Weapons, the A4 Rocket. The structure that stands today was only 1/3 of that planned for the final assembly, fuelling and launching of the A4 liquid fuelled rockets. The impressive concrete structure was never used having been damaged by bombing raids before completion. A very large crater near one wall shows the impact point of one of Barnes Wallis' Earthquake bombs which, although it didn't make a direct hit, caused enough structural damage for the Germans to abandon the facility built by slave labour. Also on display was a V1 flying bomb, plus several military vehicles and a one man midget submarine.
