The blaze, the biggest in the Scarborough area for many years, broke out on Friday evening and burned through the night.
It caused major disruption, and residents were told to stay indoors. The derelict school was empty and there were no injuries.
Police are searching for teenagers believed to be responsible for the blaze.
These photos were taken by residents, and also our photographer Richard Ponter, who pictured the scene on Saturday morning, when fire crews were still there and the area was still cordoned off.
