After hearing about Big Ben since childhood, it was quite a thrill to stand beneath it and listen as it chimed the hour. Of course, the organist in me couldn't help but think about Carillon de Westminster by Louis Vierne. The largest bell, which the nickname Big Ben actually belongs to, is massive, being 9 feet wide and over 7 feet high and weighing in over 13 tons, and is the largest bell ever cast at the Whitechapel Foundry.
