The Kent State University campus is also home to the May 4th Site, Memorial and Visitors Center, which commemorate the events of May 4, 1970, when four students were killed and nine wounded by the Ohio National Guard troops during a protest against the Vietnam War. The memorial sits on a sloped, wooded area at the northern corner of Taylor Hall overlooking the University Commons. Every spring the bloom of the 58,175 daffodils planted at the site symbolizes the nation's losses in Vietnam. For the 40th anniversary of the events, seven trail markers with descriptions, maps and pictures were installed so visitors can walk part of the campus and learn about what occurred that day. To further enhance their self-guiding walking tour, visitors can call (330) 672-6294 to hear audio narration on their cellphone by civil rights activist and NAACP Chairman Emeritus Julian Bond.
