Riordan Mansion State Historic Park

Riordan Mansion is an Arts and Crafts style residence in Flagstaff built with local Ponderosa pine and volcanic basalt. The structure was designed as a duplex and includes roughly forty rooms with distinct functional areas throughout.

The Riordan brothers, who ran a lumber operation, completed this residence in 1904 as a reflection of their business success. The building represents the prosperity that the timber industry brought to Flagstaff.

The rooms contain original furnishings and handcrafted pieces that show how successful families lived in early 1900s Arizona. Walking through these spaces, you see personal items and decorative works that reveal the daily habits and tastes of the era.

You can tour the interior only through guided one-hour visits that are scheduled regularly throughout the year. Advance registration is helpful, and seasonal programs offer special access to certain areas.

The building had advanced features for its time, including indoor plumbing, electric lighting, and central heating throughout. These conveniences were unusual in private homes of the area back then and demonstrate the family's wealth.
