Dam Those Russians

I always enjoy sitting in the Observation Lounge whenever we sail in or out of port, but see little of the passage since it's typically overnight. As we sailed out of St Petersburg, I looked at a Google map.

It looked like we'd be passing under a bridge by Kronshtadt and stayed to watch. As we approached, what looked like a naval base appeared, but no bridge, just a narrow channel.

Just past, on both sides of our ship, this came into view. It's the St Petersburg Dam, built to isolate the Bay of Neve from the greater Baltic sea.

I'm sure it's a coincidence that the structure also funnels every ship entering St Petersburg through a narrow passage next to a military base...

Safely through, the ship headed west to Tallinn, Estonia and we headed up to dinner.
