Horniman's Pleasance, Kensal, London

Pevsner's London 3: North West (with Bridget Cherry, 1991) says:

An early improvement was the RECREATION GROUND (the Emslie Horniman Pleasance) between East Row and Bosworth Road, presented by Emslie J Horniman in 1911, with – a great surprise – buildings and garden layout designed by CFA Voysey. The rectangular garden is laid out around a formal pool. It is surrounded by roughcast walls, white above a black plinth, pierced by circular openings with iron grilles. At either end are arched shelters, and above the entrance is a well-lettered inscription. The ironwork is by W B Reynolds.
