Remember the 5th of November

On the 5th November, Fireworks Day, I'd like to feature somewhere you probably haven't heard about or visited (although some people have), it is Gunpowder Park. Reclaimed from Royal Gunpowder Mills when it was used for the development and research of explosives, it sits just inside the M25 to the north of London. This slab of concrete basically says "Bang" in lots of different ways.
