Castle Bromwich, which grew into a new town, was developed approximately six miles to the east of the town centre during the 1960s. Castle Vale, near the Fort Dunlop tyre factory to the north-east of the city centre, was developed in the 1960s as Britain's largest postwar housing estate; featuring a total of 34 tower blocks, although 32 of them had been demolished by the end of 2003 as part of a massive regeneration of the estate brought on by the general unpopularity and defects associated with such developments.
