Christmas decoration light outdoor during nighttime

I took those photos in my last travel to Europe. From Paris, there are pictures from Opéra Garnier, Musée du Louvre, Avenue des Champs-Élysées and The Eiffel Tower. From London, there are pictures from London Bridge, The River Thames and The Parliament of the United Kingdom. From Italy, there are photos from Torre di Pisa and The Dolomites.
