Castles was a British soap opera following three generations of a large London family.
Its writing team included Peter Whalley who was known for his work on Coronation Street and Sally Wainwright who would go on to create Scott & Bailey and Happy Valley.
[1] The first episode aired on 31 May 1995 at 7.30pm before settling into what was supposed to be its regular timeslot of Tuesday and Thursday at 8.30pm.
Halfway through its run, with audiences averaging 3.2 million, BBC head of drama Charles Denton admitted that the show had not been a success, stating "A piece which sits in the middle of the schedule has obligations to deliver rather fuller levels of audience and enthusiasm than, I'm afraid, has happened with Castles".
