This painting by George Shepherd is held in a private collection.
It is a view looking north from the Herne Hill side of the Triangle. Now the home of the Fox on the Hill. In the distance you can see a row of large houses and the top of Denmark Hill Chapel.
The chapel was built in 1773. “It was said that the inhabitants of Camberwell Green area “found it very difficult or impracticable to procure Seats or accomodation to attend divine service in the Parish Church of Camberwell” (St Giles)”. It was demolished in 1846, to allow the building of St Matthews Church, on the site of the current Dental Hospital.
