The municipal borough of Peterborough was incorporated in 1874, and covered the urban area only. In 1974 it was abolished and replaced by a wholly new Peterborough City Council, covering both the urban area and the outlying rural areas which formerly formed part of the Liberty. In 1998 this in turn was abolished and replaced by a new unitary authority, which has also adopted the name Peterborough City Council.
The main series of signed minutes is held at Peterborough City Hall.
