 The mall opened in 1979 with anchor stores Goldblatt's and Montgomery Ward.
 Competitive and economic factors sent the mall into steady decline and national retail chains left throughout the 1990s until the mall was ultimately sold for redevelopment in 2001 then closed and largely demolished in 2002.
