After spending nearly 5 years in a downward spiral, the mall was knocked down in 1997. The Regal Charles Towne Square Stadium 18, a state-of-the-art multiplex cinema, was built on the former mall site. The megaplex was dedicated in May 1999 and was in operation for over 20 years. It was shuttered in December 2019 and demolished soon after.

Marriott's Courtyard Charleston North / Coliseum hotel also opened in 1999. It took the place of the freestanding Penney's Auto Center, which had become a Firestone Car Care in 1983.
