Penshaw Monument walk

From Wikipedia: "The Penshaw Monument (officially the Earl of Durham's Monument) is a memorial in the style of an ancient Greek temple on Penshaw Hill in the metropolitan borough of the City of Sunderland, North East England. It is located near the village of Penshaw, between the towns of Washington and Houghton-le-Spring in historic County Durham. The monument was built between 1844 and 1845[a] to commemorate John Lambton, 1st Earl of Durham (1792–1840), Governor-General of British North America and author of the Durham Report on the future governance of the American territories. Owned by the National Trust since 1939, it is a Grade I listed structure."
