Pasadena’s Orange Grove Boulevard has long been known as “Millionaire’s Row” for the lavish mansions that once lined the street.

Though many of those mansions are long gone, chewing gum magnate William Wrigley’s 3-story, 21-room home lives on as the headquarters of the Pasadena Tournament of Roses Association. One of six palatial estates the Wrigleys owned across the country, the home was reportedly Mrs. Wrigley’s favorite, as she enjoyed watching the Rose Parade pass by from her vantage point on the porch.

After Mrs. Wrigley’s death in 1958, the home was gifted to the City of Pasadena with the stipulation that it serve as the Tournament’s headquarters. Inside the home, 125 years of Tournament of Roses memorabilia are on display, including the formal portrait of the reigning Rose Queen, crowns and tiaras worn by former queens and princesses, and a unique Waterford crystal bowl commissioned for the Tournament’s centennial celebration.

The grounds are open to the public year-round, as are the All-America Rose Selection test gardens. The house itself is open to the public from 2-3pm every Thursday from February to August.
