Sinkhole in Plantation Gardens, Norwich

On 9th April 2016, a 20-foot-deep sinkhole appeared at Norwich’s Plantation Garden, causing subsidence cracks to the neighbouring hotel on Earlham Road. This is a stone’s throw away from the 1988 sinkhole which swallowed a double-decker bus. The Plantation Garden is itself an old chalk quarry, with multiple mining tunnels leading off it. It is the collapse of a mining tunnel that is thought to have caused this sinkhole.
