The Baltic Exchange was a building located at 24–28 St Mary Axe in the City of London and occupied by Baltic Exchange Ltd, a provider of information on maritime transportation markets. A historic landmark, the Baltic Exchange building was architecturally known for its cathedral-like trading hall and its stained glass war memorial. It was damaged in a bombing in 1992. The site is now occupied by 30 St Mary Axe ("The Gherkin"); the stained glass can be seen at the National Maritime Museum.
