The city within a city is a model of building resurrected from Rome and Trajan's forum. Usually associated with skyscrapers, the city within a city is a development where space is used very efficiently to include a large number of programs of different functions, like residential, office, and education. Albany, NY is the location of one such city within a city. The state government built a large plateau that contains underground parking and roads, with large high-rise buildings that contain vast amounts of office space, a museum, and meeting space. A massive open-air plaza connects all these spaces together.
