Christ Church's Tom Tower at sunset, from inside the quad. "Great Tom" (the bell inside) rings every its traditional curfew of 101 tolls each evening beginning at 9:05pm, as it has since the college's 16th century founding (with time off for periodic recastings in the 16th and 17th centuries). Asked how he managed the correct number of strokes each time, the man who used to ring it earlier this century replied "I just count 50, then I count 51."
"Great Tom is cast,
and Christ Church bells ring one, two three, four, five, six,
and Tom comes last"
