The Duke of Edinburgh visited Lincoln College during 1973. He was in New Zealand 11-14th October 1973. When the Duke of Edinburgh came to the College, his car, by arrangement, was stopped a short distance from the college and he was invited to leave the limousine, sit on a bale of hay in a tractor - drawn trailer in company with students in football jerseys, and thus obtain his first introduction to Lincoln College (Source).
