Love padlocks , Tiergarten , Berlin.

A busy first day in Berlin.

Google gives this explanation of the padlocks.

Berliners and guests in love from all over the world fix ,as a symbol of their eternal ties ,small individually designed padlocks to the bridge parapets of the metropolis on the river Spree. The iron tokens of love are decorated with engraved names, a date, sometimes also hearts or intertwined wedding rings. The couples then throw the keys together into the river Spree. Apparently this custom originates from Italy, the homeland of Romeo and Juliet. However, in Rome such proofs of love are by now banned in public areas after a lantern snapped under the burden of the luchetti dell´amore.
