Photos: Old and new views of the Owl's Club

The ornate Owls Club building at 378 N. Main Ave. lies amid other stately old homes and offices in the historic El Presidio neighborhood, where it was built to house a club of bachelors who called themselves owls because they wanted to “nest” while waiting to find brides. The Tucson-based Center for Biological Diversity plans to move into the 112-year-old Owls Club mansion downtown in June, after buying it for $1.3 million.
