Wash-house foundation stone
SW1, Great Smith Street, Westminster Archives Centre
The foundation stone is immediately to the right of the entrance.
The second floor bay window has some lovely relief work by Henry Poole showing swimmers - naked classical Greek young men. Ornamental Passions has good photos of these. Bas relief is not the ideal medium for showing bodies underwater.
In the 1990s the baths were replaced with the Westminster Archives Centre, a community centre and meeting space called the Abbey Centre. Historic England has an 1893 photograph.
