Plummer Building: Offices, Tours & Architecture

Adorned with bronze doors weighing two tons and marble floors imported from around the world, this iconic symbol of Mayo Clinic is now a designated National Historic Landmark. Named for Henry S. Plummer, M.D., it was once the home of all medical facilities and an extensive library on the Mayo Clinic grounds. Today, the Plummer Building remains an integral part of Mayo Clinic, accommodating many administrative, academic and support functions. At night, the bell tower lights up the Rochester skyline, and during the holiday season, the south facing wall is illuminated with colored lights.
The Kahler Grand Hotel puts you within moments of this and other nearby local sights. Explore the best of Rochester and save on your stay with our specials.
