conduct what came to be known as the "Midnight Raid" on the Naperville courthouse. As Wheatonites fled back on Wheaton-Naperville Road, Napervillians were able to secure some of the last remaining records, which were then taken to the Cook County Recorder in Chicago for safekeeping. During this time, Naperville was mounting a lawsuit against Wheaton accusing election judges of leaving their posts for lunch during the vote when duplicate ballot stuffing allegedly occurred. As the courts deliberated the fate of the county seat, the records were destroyed in the Great Chicago Fire of 1871. Shortly thereafter, Wheaton was officially proclaimed the county seat. As demand for space increased, the courthouse was rebuilt in 1887 at a cost of $69,390, modeled after the courthouse in Aledo. This structure was used for the next 94 years until the county's rapid growth prompted the building of a brand new complex. The old courthouse is listed on the National Register of Historic Places, and was formerly used by National Louis University until National Louis moved to Lisle in 2004. It is currently being developed into luxury condominiums. On November 2, 1990, the courthouse moved to a building about two miles (3 km) west in a new complex at the corner of County Farm Road and Manchester Road. It was built at a cost of $52,500,000 and includes a judicial building. In 1992, the county sued the architect and contractor for $4 million after several employees became ill from the ventilation system. In the end, however, the county received only $120,000 for minor repairs and the jury sided with the defendants, finding that the alleged problems were caused, primarily, by the county's negligent operation and maintenance of the ventilation system. Expansion Wheaton has rapidly expanded since the 1950s, although population growth has slowed since the early 1990s, as the city has become increasingly landlocked. Downtown lost much business after the county courthouse facility moved two miles (3 km) west in 1990, but in the decade since, the downtown has seen a renaissance of sorts, with the creation of several significant condominium and business developments. One of the most recognizable landmarks of the city is Wheaton Center, a 758-unit apartment complex on in downtown Wheaton. The six building complex includes two twenty-story high-rise buildings built in 1975. In 1887, Wheaton prohibited the sale of alcoholic beverages, a ban which lasted until 1985 and applied to all
