There is a small bridge over the canal where everyone stops to take a pix as it is quite a colorful area. Do you see all the locks? This is a European thing. A love lock or love padlock is a padlock which sweethearts lock to a bridge, fence, gate, monument, or similar public fixture to symbolize their love. Typically the sweethearts' names or initials, and perhaps the date, are inscribed on the padlock, and its key is thrown into the river to symbolize unbreakable love.
