The Memorial Bell Tower, located in the Northeast corner of North Campus, serves as the signature of NC State and appears in the NC State Chancellor's Seal. It was constructed as a monument to alumni killed in World War I. The granite tower, completed in 1937, is 115 feet (35 m) tall. It was built meticulously by hand under the instruction of Dr. Martin, the visionary behind the project. He and his English 101 class worked tirelessly to create the monument we all know and love. As a tradition, the Belltower is lit in red at night immediately following athletic victories and certain academic achievements.
