itself is disproportionate: the bottom has been cut off to accommodate a rise in street level, which can be seen in the steps leading down to the foot of L staircase in the gate tower. The college hall, originally built at the very start of the 16th century, was restored in 1875–1879 by George Gilbert Scott the younger. The lawn of First Court is famously round, and a wisteria sprawls up the front of the Master's lodge. Second Court is fully built up on only three sides, one of which is formed by the 1640s Fellows' Building. The fourth side backs onto the Master's garden. The Stevenson Building in Third Court was designed by J. J. Stevenson in the 1880s and was extended in 1905 as part of the College's Quadcentenary. In 1947 Professor Albert Richardson designed a new cupola for the Stevenson building, and a second building, the neo-Georgian Chancellor's Building (W staircase, now known as The Blyth Building), completed in 1950. Third Court's Memorial Building (Y staircase), a twin of the Chancellor's building, also by Richardson, was completed in 1953 at a cost of £80,000. Third Court is also noted for its display of irises in May and June, a gift to the college in 1946. The controversial tiered concrete New Court (often dubbed "the Typewriter") was designed in the Modernist style by Sir Denys Lasdun in 1966–70, and was described as "superb" in Lasdun's obituary in the Guardian. Design critic Hugh Pearman comments "Lasdun had big trouble relating to the street at the overhanging rear". It appears very distinctively in aerial photographs, forming part of the northern boundary of the college. An assortment of neighbouring buildings have been absorbed into the college, of which the most notable is the Todd Building, previously Cambridge's County Hall. Through an arch in the Fellows' Building is the Fellows' Garden. It includes two mulberry trees, of which the older was planted in 1608, the same year as Milton's birth. Both trees have toppled sideways, the younger tree in the Great Storm of 1987, and are now earthed up round the trunks, but continue to fruit every year. Swimming pool Christ's College is one of only 5 colleges in Oxford or Cambridge to have its own swimming pool. It is fed by water from Hobson's Conduit. Recently refurbished, it is now known as the 'Malcolm Bowie Bathing Pool', and is thought to
