Ponte Milvio is a bridge located in northern Rome. This bridge is interesting as the lamp post is laden with locks.
There is a tale here where you write your name and your lover's name on the lock, lock it on a lamp post and throw away the key in the river. Your love would be eternal.
Cartcart and I didnt do that though, we are both too old and too cynical :-P
