Travelog post for: Squizzle

Mummy, daddy, big bro and I went to Holyhead. We wanted to visit the Maritime Museum but unfortunately it was closed. Still, they had a few exhibits outside.
This is a diving observation chamber used in World War II for recovering matals from shipwrecks. The information for the exhibit said that it had a working depth of 300 metres, and that the chamber had enough oxygen for three hours. There was a telephone cable too so that the diver could contact the salvage ship above and direct the grab thing to get the valuable metals.

There's also an air raid shelter, but again, we were out of season to visit inside.
