City of Westminster
Site: Sister Thomas (1 memorial)
W1, Foley Street, John Astor House, Middlesex Hospital
At Lost Hospitals we learn that this was a Nurse's Home, opened in 1931. So it's where Sister Thomas lived, not where she displayed her heroism, which was presumably at the main Middlesex Hospital in Mortimer Street which must be the building outside of which Pathé News filmed Sister Thomas receiving the award from George V and Queen Mary.
