When Wachovia and First Union merged, Charlotte's One, Two, and Three First Union buildings became One, Two, and Three Wachovia Center (respectively), and the 55-story First Union Financial Center in downtown Miami became the Wachovia Financial Center. The merger also affected the names of the indoor professional sports arenas in Philadelphia and Wilkes-Barre, Pennsylvania. Formerly known as the First Union Center and the First Union Spectrum (both Philadelphia) and First Union Arena (Wilkes-Barre), they became the Wachovia Center, Wachovia Spectrum, and Wachovia Arena at Casey Plaza, respectively. In 2010, following Wachovia's merger into Wells Fargo, the Spectrum was demolished and the other venues became the Wells Fargo Center and the Mohegan Sun Arena at Casey Plaza.
