5 /5 Arthur: I had a really good time here. The place is small, but the story behind the Thames Tunnel is huge, and the team makes it come alive. The guided talk was the highlight for me. You can tell they genuinely enjoy sharing the history. Going down into the old shaft was a surprise in the best way, and it gives you a real sense of what Brunel pulled off. Easy visit, interesting from start to finish, and worth the trip if you like discovering places with real character.
