4D Cityscape is a multi-layer puzzle that is fun, challenging, and educational. Assemble the first two layers of the puzzle to form a map of the city’s streets, islands, roads, railways, parks, and geography. When the base layers are complete, you’re ready to embark upon the 4th Dimension, Time, located on the third layer of the puzzle. As you work your way through the Time Poster you are placing each building in chronological order as if history is happening before your eyes! The year of the last building placed on the map represents the year you are in the puzzle. Learn how a city develops and evolves, explore historic buildings and architectural styles, get to know the geography of an area, and discover the defining moments in history!
