Originally built around 1100, it was named after St Dunstan, a 10th-century monk and Archbishop of Canterbury. The church was severely damaged during the Great Fire of London. Rather than a total rebuild, it was patched up, and Sir Christopher Wren added a stunning Gothic-style tower and steeple in 1695. During World War II, the church was largely destroyed by German bombing. Only Wren's tower and the north and south walls remained standing. Instead of rebuilding after the war, the City of London Corporation decided to turn the ruins into a public garden, which officially opened in 1970.
