The Willmore is an eleven-story, L-shaped residential building with reinforced concrete construction located in downtown Long Beach. The structure contains multiple apartment units ranging in size along with underground parking and basement laundry facilities.

Built in 1925 and opened in 1926 by the Trewitt-Shields Company, The Willmore was first called The Stillwell. It was designed by Fisher, Lake and Traver, the architects of the Hollywood Roosevelt Hotel, and listed on the National Register of Historic Places on May 20, 1999. Its current name honors William E. Willmore, developer of Willmore City, a forerunner of Long Beach.

The name honours William E. Willmore, developer of Willmore City, the settlement that preceded Long Beach and gave its neighbourhood its name. The building was first called The Stillwell before taking his name. Its Renaissance Revival and Beaux-Arts design comes from Fisher, Lake and Traver, the architects of the Hollywood Roosevelt Hotel.

The Willmore stands in downtown Long Beach, listed on the National Register of Historic Places since May 20, 1999. Its entrance faces the street at the base of the ten- and eleven-story wings, and an underground parking garage serves the building. Visitors can walk the surrounding downtown blocks to see the reinforced concrete facade from street level.

The building was designed as a U shape, but only one wing was ever completed, leaving the L-shaped plan with a ten-story wing and an eleven-story wing. Its architects, Fisher, Lake and Traver, also designed the Hollywood Roosevelt Hotel.
