Marquess of Westminster Memorial Fountain

The Italian Renaissance-style memorial to Richard Grosvenor, 2nd Marquess of Westminster stands at the junction of Pimlico Road and Avery Farm Row in London. Grosvenor was a politician and developer who - before his death in 1869 - was an early patron of Chester architect John Douglas.

Erected around 1870, the four faces of the Portland stone and granite drinking fountain are covered by enamel mosaics by Salviati.

 
Salviati also made the mosaic reredos for the Douglas designed St. John's Church in Aldford, tying it back to Grosvenor through that additional connection.
