CITY OF MEXICO - Cornwall & Devon

The City of Mexico is one of those wrecks that really sticks with you. Dropping down to 49 metres, you’re greeted by a grand old steamship, her 78-metre length stretched out on the seabed. She went down in 1916, stopped and sunk by a German submarine, carrying coal from Blyth to Rochelle. We love that sense of history, how intact she still is, even after all these years. Her triple-expansion engine is a prominent feature, a complex tangle of machinery now cloaked in vibrant jewel anemones. We always suggest taking a good torch. The light penetration at this depth is limited, but your beam will pick out the reds and oranges, making the colours pop. Look for conger eels peering from dark recesses, their thick bodies disappearing into the gloom. Visibility here can be excellent, though it's always worth checking conditions. Our favourite part is exploring the holds, imagining the cargo she once carried. It's a dive for experienced deep wreck divers who appreciate a substantial piece of maritime history.
