I have to say these photos don't do the 14 Inch Naval Railway Gun justice. It's BIG and very impressive. However the trees have overgrown around the gun and in summer months you can't see the entire gun carriage from any angle. If you want to photograph it well you're best to come in the winter months when the leaves are gone from the trees.
