As the oldest town in DuPage County, Naperville was the center of rural DuPage County life for over a century. In fact, it falls in DuPage and Will Counties. By the 1970s, it had become the fastest growing city with a population that tripled in two decades. A 50-block area of old Naperville, comprised of vintage homes, has been designated a National Historic Landmark District. Naperville’s central business district is home to many charming shops and cafes, supplemented by a number of local plazas and shopping centers. School Districts 203 and 204 serve the community and acclaimed colleges are also available in Naperville or neighboring suburbs. Naperville’s 1,200-acre Park District has won the Sports Foundation gold medal for outstanding recreational programs and facilities. Created exclusively through local volunteer contributions, the Riverwalk is a unique park overlooking the DuPage River.
