Three Cambridge University buildings have received grade II listed status.
The three post-war structures, within the grounds of Fitzwilliam College, are the Central Hall Building, the New Court and the Chapel.
The striking designs include a flamboyant gravity-defying lantern, a worship space resembling a floating ship, and a distinctive stepped design where each floor has a different appearance inside and out.
The Central Hall Building was designed by Sir Denys Lasdun, the architect who also designed the National Theatre in London.
Historic England spoke to Star Radio:
"These three fantastic buildings form a reinterpretation of the traditional Cambridge college.
"They were designed for an optimistic, forward-looking, post-war England, when university access was rapidly expanding, and new democratic ideals were finding architectural expression.
"Each building is highly individual, with thoughtful detailing and an imaginative approach, a testament to the exceptional creativity of Lasdun and MJP in partnership with Fitzwilliam’s academic community."
