This puzzle recreates Paris' famous skyline, not only in three- dimensions, using scale-model buildings, but also along the fourth dimension of time; spanning 650 years of architectural history. The puzzle includes 80 building replicas that depict The City of Light as it appeared as far back as 1345 through to 2015, and includes such iconic structures as the Eiffel Tower, Arc de Triomphe, and Notre Dame Cathedral. The base of the puzzle is a traditional 2D jigsaw puzzle composed of 870 pieces that forms the city's street layout and islands. During the process of constructing the base map, one learns about Paris' neighborhoods, streets, museums, and more. Once the puzzle base is complete, the vertical building of Paris begins by placing 80 buildings and skyscrapers in chronological sequence. This is done by following the enclosed Time Poster.
