The Purdue Centennial Marker is located in front of the Materials Science and Electrical Engineering Building along Northwestern Avenue. It was dedicated in 1969 during the Purdue Centennial Celebration and displays Purdue’s crest, which was specifically designed for the centennial. Beneath this marker, a sealed copper box containing Purdue artifacts from 1969 (including a letter from then-President Hovde to Purdue’s president in 2069), is buried under nearly a foot of concrete.
