One of the most recognized landmarks in the world, the Tower Bridge is considered the defining landmark in London. The bridge was completed in 1894 and is one of the most visited locations in the city. This image, taken across the River Thames near Butler's Wharf Pier, shows the bridge but also the modern buildings of London's commercial section framed by the bridge. The key to this puzzle is the lighting of the bridge against the sunset sky. The bridge pieces will be the ones sorted out first and the water and the sky will come after. Both of these will provide a bit of a challenge as they are relatively solid colors with some clouds in the sky and the reflections of the bridge on the water. This grows into an iconic image of one of the world's most recognized structures. Clementoni puzzles are crafted in Italy using premium quality materials to enhance the carefully selected imagery featured on each puzzle.
