Mayo Clinic Lighting Program

The Plummer Building on the Mayo Clinic campus in Rochester, MN is named for scientist, physician, and engineer Dr. Henry S. Plummer, whose tenure spanned Mayo's formative years from 1900 until his death in 1936. His genius and energy were essential to Mayo's early success and development. The tower at the top of the Plummer Building houses Mayo Clinic’s Carillon. The Carillon Tower is one of Mayo Clinic’s and the City of Rochester’s most prominent and recognizable architectural features and is beautifully illuminated each night. With increasing frequency, disease-specific nonprofit organizations have requested that the Carillon Tower be lighted in a specific color to heighten awareness of their cause.

In the past, other lighting requests have included commemorating those lost in terror attacks, the loss of Mayo staff and certain holidays.

Non-profit health and wellness related organizations have the opportunity to request that the Carillon Tower be lighted a specific color to heighten awareness of their cause.
