for about two euros you can climb the 533 steps of the south tower of the cathedral to the very top, about 100 meters up, passing through the bell chamber that houses the st. peters bell, which at 24,000 kg is the largest freely swinging church bell in existence. it is a long climb (especially when you're carrying a bag with your cameras and laptop) and once i had walked up and back down my legs wouldn't stop shaking.
aside from a small postcard depicting the architectural blueprints for the cathedral, my only memoirs were two small bottles of kolner domliqueur, which is a reproduction of liquor that the monks of the cathedral made centuries ago using mostly herbs. it was a little too sweet for my tastes, but the bottles make great keepsakes.
