On the night of 22 April 1941, during the the blitz, over 70 civilians were killed, including a mother and her six children, when a bomb fell on the shelter near the Planetarium. The bomb shelter consisted of a series of underground tunnels which many had long-presumed lost but were rediscovered in 2006. The bomb blast was so big that human remains were found in the tops of trees. In 2006 an appeal was made to raise money for a public sculpture to honour those who lost their lives.
