The long-lost gardens of Nant Gywllt House, demolished to create a new reservoir system in mid-Wales, have been exposed by the recent drought.

The former 7-bed manor house with a farm of 200 acres meadow-land, located on the densely wooded slope south of the Claerwen, was occupied by poet Shelley and wife, Harriet Westbrook, daughter of an inn-keeper, during April-June 1812 with hopes of leasing it as their home.

Nant Gwyllt House was demolished to create a new reservoir system in the adjacent Elan and Claerwen Valleys of mid-Wales to provide a gravity-fed water supply for the population of Birmingham. Today, the falling water level of the Caban Coch reservoir has revealed the stone garden walls with their stone doorways and a stone bridge, all normally submerged out of sight
