BOLTON’S hidden history will be revealed during Heritage Open Days this weekend.

Bill Naughton’s original script for Alfie, the chilling interrogation room of a famous Bolton martyr and arguably the finest rooftop view in the town all feature during the English Heritage backed programme of activities.

Here are twelve of the borough’s attractions that will host special events, many offering the chance to glimpse rarely seen archives and off-limit areas.

Elsewhere features Bill Naughton’s original script for Alfie. Pictured is collections access officer, Caroline Fury, in the archive room.  Limited places left for 45 minute tours on Saturday 10am and 11am and Sunday 11am and 12noon. Call 1204 332211 to book.
