This is Blakeymoor School, quite soon after it was built (c1911). The arched doorway, where the steps can be seen, fronts onto Duke Street. The other wing, which is actually on Blakeymoor itself, is where the swimming pool was located in the basement. The gate and external steps down to the basement, would be/still are, approximately between the two pillars on the extreme right of this view (Please click on the photo, to expand it). The whole basement area, over both wings, are now used for teaching purposes, by Blackburn College, who own the premises. The pool was boarded over in 1999 and the area divided into 3 - 4 classrooms. The pool is still there to this day (empty, I hope) and can be accessed via a hatch in the first classroom.
Didn't Russell Harty (chat show host) teach here briefly, before moving to Giggleswick and then onto TV fame?
