Milvio Bridge, Rome.

 On my trip to Rome I discovered this unique bridge which has padlocks that lovers leave there to represent their relationship. It as a strong simbolism attached to it, the locked padlock means how strong is the relationship between the two who leave it there. It all began when the author Federico Moccia wrote a novel about that tradition where the lovers must lock the padlock to a lamp or some chains on the bridge and throw the key behind them into the Tiber river, which means love forever. I searched the story on the web, and you can read more on wikipedia and on the official website.
