Thayer Monument is a white granite monument and statue of Sylvanus Thayer at the United States Military Academy, designed by C. Conrad and first unveiled in June 1883. Thayer is known as the "Father of the Military Academy" for the profound and lasting impact of his superintendency during the academy's early years. The monument's location has changed over the years. It first occupied the southwest corner of the Plain, but it currently sits at the intersection of Washington and Jefferson roads, adjacent to the Beat Navy tunnel on the northwest corner of the Plain. The memorial is the sight of multiple memorial ceremonies during the year as West Point reunions hold a parade and memorial service at the site.
