In the 1920s, the world's largest goldfish farm was relocated to the area where the mall stands today.

The mall structure was designed by Architectonics, Inc. of Dallas and Chicago with each department store hiring its own architect.

In 2008, the mall underwent a renovation, relocating the carousel and constructing a play area in its place.

As of 2023, Spencer Gifts was the last long-term tenant remaining from the opening era of the mall in their original location on the upper level.

John's Incredible Pizza shuttered its doors this year due to the mall management to repurposing the space, only leaving Buena Park and Carson locations.

During the COVID-19 pandemic, the Westminster Mall saw a dramatic decline in sales, due to many of its businesses laying off employees, and their closures.

Because of this, in April 2023, the City of Westminster approved a redevelopment plan to utilize the mall's main building, for mixed-use housing, lodging and retail.

Route 25, which runs along Goldenwest Street on the eastern side of the mall, provides access from Huntington Beach and northern Orange County, and Route 64, which runs along Bolsa Avenue on the southern side of the mall, provides access from cities to the east such as Garden Grove and Santa Ana.
