It is said that once, one could walk from Cambridge to Oxford crossing only Trinity land. Start outside the gatehouse on Trinity Street: Henry VIII founded the college in 1546 by merging two existing ones. His statue stands proud; below him, the coat-of-arms of Edward III, founder of one of the earlier institutions, and below that, the shields of his sons. Look especially at the feathers of the Prince of Wales, still used by Prince Charles today, and a blank shield, Edward's youngest son died in infancy. To the right of the gatehouse, an apple descended from the tree which prompted Isaac Newton to make his theory of gravity.
