The first buildings comprised a single court (now called Old Court) containing all the component parts of a college – chapel, hall, kitchen and buttery, master's lodgings, students' rooms – and the statutes provided for a manciple, a cook, a barber and a laundress. Both the founding of the college and the building of the city's first college Chapel (1355) required the grant of a papal bull. The original court was the university's smallest at only by , but was enlarged to its current size in the nineteenth century by demolishing the south range. The college's gatehouse is the oldest in Cambridge. Chapel The original Chapel now forms the Old Library and has a striking seventeenth-century plaster ceiling, designed by Henry Doogood, showing birds flying overhead. Around the Civil War, one of Pembroke's fellows and Chaplain to the future Charles I, Matthew Wren, was imprisoned by Oliver Cromwell. On his release after eighteen years, he fulfilled a promise by hiring his nephew Christopher Wren to build a great Chapel in his former college. The resulting Chapel was consecrated on St Matthew's Day, 1665, and the eastern end was extended by George Gilbert Scott in 1880, when it was consecrated on the Feast of the Annunciation. Expansion An increase in membership over the last 150 years saw a corresponding increase in building activity. The Hall was rebuilt in 1875–1876 to designs by Alfred Waterhouse after he had declared the medieval Hall unsafe. As well as the Hall, Waterhouse designed a new range of rooms, Red Buildings (1871–1872), in French Renaissance style, designed a new Master's Lodge on the site of Paschal Yard (1873, later to become N staircase), pulled down the old Lodge and the south range of Old Court to open a vista to the chapel, and finally designed a new Library (1877–1878) in the continental Gothic style. The construction of the new library was undertaken by Rattee and Kett. Waterhouse was dismissed as architect in 1878 and succeeded by George Gilbert Scott, who, after extending the chapel, provided additional accommodation with the construction of New Court in 1881, with letters on a series of shields along the string course above the first floor spelling out the text from Psalm 127:1, ("Except the Lord build the house, their labour is but vain that build it"). Building work continued into the 20th century with W. D. Caröe as architect. He added
