Cadby Hall was built in 1873 as a piano factory. Our picture comes from Cadby Hall: "Built to the design of Lewis H. Isaacs, Cadby Hall was faced in red Fareham bricks and Portland stone with terracotta panels over the first floor windows, the keystones of which contained nine carved portraits of celebrated composers." There are a few photos of Cadby Hall on the web but most don't show the first floor windows on the front of the building. This image does, all 9 of them, and we think we can just about see that there are keystones.
Cadby Hall was demolished in 1983 and we have no information that the keystones were rescued.
