Regarded as one of the most beautiful of the Oxford and Cambridge colleges, Magdalen is also one of the most visited. It stands next to the River Cherwell and has within its grounds a deer park and Addison's Walk. Magdalen College School also lies nearby. The large, square Magdalen Tower is a famous Oxford landmark, and it is a tradition since the days of Henry VII that the college choir sings from the top of it at 6 a.m. on May Morning. The college's current president, Professor David Clary FRS, was earlier a Fellow and Senior Tutor at Magdalene College, Cambridge.The Great Tower was built between 1492 and 1509 by William Orchard, and is an imposing landmark on the eastern approaches to the city centre. The hall and chapel were built at similar times, though both have undergone some changes in the intervening years.
