Knock John Naval Fort

2019 (United Kingdom)

Thames Estuary Maunsell Forts: Part 1 - Knock John Fort & Grain Tower.

This was a very special boat trip for my Dad's Birthday & we saw some amazing sites! Knock John Fort is a naval fort 9 miles out past the Thames Estuary. It's a huge imposing site in the middle of the ocean & one of the most impressive and remote structures I will ever see. We also passed the sunken SS Richard Montgomery, an American Liberty ship built during World War II. Last on the trip that day was the Grain Tower, which is a 19th century gun tower which you can reach it at low tide. Having seen it at high tide, I certainly wouldn't want to get stuck there!
