the insurgency of the Cowling clique ("a strong mind trapped in its own glutinous frustrations"), and to bring the college back to a condition in which students might actually want to go there. Neither side won this struggle, which soon became a campaign to drive Trevor-Roper out of the college by grotesque rudeness and insubordination. In a review of Adam Sisman's 2010 biography of Trevor-Roper, the Economist wrote that picture of Peterhouse in the 1980s was "startling", stating the college had become under Cowling's influence a sort of right-wing "lunatic asylum", who were determined to sabotage Trevor-Roper's reforms. In 1987 Trevor-Roper retired complaining of "seven wasted years." Peterhouse may have been one of the sources of inspiration for Tom Sharpe's Porterhouse Blue. In the 20th century Peterhouse has established a more modern and welcoming reputation. Buildings and grounds Peterhouse has its main site situated on Trumpington Street, to the south of Cambridge's town centre. The main portion of the college is just to the north of the Fitzwilliam Museum, and its grounds run behind the museum. The buildings date from a wide variety of times, and have been much altered over the years. The college is reputed to have been at least partially destroyed by fire in 1420. The entrance of the college has shifted through its lifetime as well, with the change being principally the result of the demolition of the row of houses that originally lined Trumpington Street on the east side of the college. In 1574, a map shows the entrance being on the south side of a single main court. The modern entrance is to the east, straight onto Trumpington Street. First Court The area closest to Trumpington Street is referred to as First Court. It is bounded to the north by the Burrough's Building (added in the 18th century), to the east by the street, to the south by the Porters' lodge and to the west by the chapel. Above the Porters' lodge is the Perne Library, named in honour of Andrew Perne, a former Master, and originally built in 1590 to house the collection that he donated to the college. It was extended towards the road in 1633 and features interior woodwork that was added in 1641–48 by William Ashley, who was also responsible for similar woodwork in the chapel. Electric lighting was added to the library in 1937. The area above the Perne
