Trace almost a full millennium of London's history as you assemble this remarkable four-dimensional geographic puzzle. After putting together the city map with glow-in-the-dark streets, you'll see what the London looked like in the year 1078. The first completed layer of the puzzle shows London in 1666, the year that the Great Fire swept through the city over three days. The second layer of the puzzle will show London as the skyline is slated to appear in 2015. With more than 1,230 pieces, this is the most challenging 4D Cityscape puzzle yet.
