Once you step inside, you find yourself in the Burgerzaal, or the Citizens Hall. This spectacular room is nearly 30 meters high and was designed to be the heart of the city. Look at the floor beneath your feet. You are walking across massive marble maps of the eastern and western hemispheres, along with a map of the northern stars. During the 1700s, these maps told every visitor that Amsterdam was the literal center of the universe. Above the doorways, you will find sculptures representing the four elements: earth, water, fire, and air, all watching over the hall. At one end, a massive statue of Atlas carries the heavens on his shoulders, symbolizing the city's global reach. Fun fact: the maps actually contain regions like New Holland, which we now know as Australia, shown just as the Dutch explorers were first mapping it in 1644.
