As far as I know, Belgrade doesn't yet have a Bridge of Lovers' Locks. There's one in Vrnjacka Banja that's quite impressive. The other day I came upon this lock, Buby and Beby's, whoever they may be, hanging on the bars of a door of Kalemegdan Park's Roman well.
Let's see how many locks are to follow....
Is there a lock-covered Lovers' Bridge in your city?
P.S. Just remembered this earlier post of mine about locks.
Daily Haiku
Fasten the lock tight
Lovers' names written for all time
Throw away the key
