 It was opened in 1933 and accommodated both Peterborough city council and the former Soke of Peterborough county council.Under the Local Government Act 1888, the ancient Soke of Peterborough formed an administrative county in its own right, with boundaries similar, although not identical, to the current unitary authority.Nonetheless, it remained geographically part of Northamptonshire until 1965, when the Soke of Peterborough was merged with Huntingdonshire to form the county of Huntingdon and Peterborough.
