William Wrigley, Jr. Summer Cottage

The William Wrigley Jr. Summer Cottage is a colonial revival mansion perched on Mount Ada with white columns and balustrades overlooking Avalon Bay. The building features classical architectural details and expansive terraces that take advantage of the hilltop location and water views.

William Wrigley Jr., founder of the chewing gum company that bore his name, commissioned architect Zachary Taylor Davis to design and build this residence between 1919 and 1921. The construction during this period made it a notable example of residential architecture from the 1920s.

This estate reflected the lifestyle and social standing of one of America's most prominent business families during the early 20th century. Guests who visited the property experienced the kind of luxury and hospitality that defined the era's wealthy circles.

The property now operates as The Inn on Mt Ada, welcoming overnight guests who want to experience the historic residence firsthand. The hilltop location means visitors should plan to walk or use local transportation options to reach the entrance.

A small pet cemetery along the pathway to the mansion holds the graves of the Wrigley family's animals. This quiet resting place reveals how much the family valued their animal companions.
