The Coral Court Motel was a 1941 U.S. Route 66 motel constructed in Marlborough, Missouri and designated on the National Register of Historic Places in St. Louis County in 1989 as a valuable example of the art deco and streamline moderne architectural styles. It expanded to 77 rooms in the heyday of automobile tourism on US 66, only to decline after the highway was bypassed by Interstate 44 in the 1970s and close its doors forever in 1993. Despite strong local efforts advocating historic preservation, it was demolished in 1995 for a suburban housing development now known as Oak Knoll Manor.
