Memorial Tower, Clock tower at Louisiana State University campus, United States.

Memorial Tower, also called the Campanile, is a 175-foot clock tower in the center of Louisiana State University's campus in Baton Rouge. The Italian Renaissance structure, associated with architect Theodore Link, was erected in 1923 and dedicated in 1926. Its rotunda holds bronze plaques naming 1,447 fallen Louisiana soldiers of World War I, and the interior also houses a military museum.

Construction of the tower began in 1923 and was completed in 1926 as a memorial to Louisiana soldiers who died in World War I. The structure was built after the war to honor those lives lost.

The rotunda inside the tower displays bronze plaques inscribed with the names of 1,447 Louisiana soldiers who died in World War I. The tower also houses a military museum. The surrounding plaza hosts the university's annual Christmas Tree Lighting and the student government's spring inauguration.

The Westminster Chimes sound every quarter-hour until 10 PM, and the university's alma mater is played at noon. The chimes fall silent after 10 PM except on Valentine's Day, when they ring at midnight for the kissing tradition. The tower interior, with its rotunda and military museum, cannot be entered without prior permission.

A superstition turned tradition holds that to become an official LSU student, one must be kissed under the tower when the chimes ring at midnight. The chimes now stop at 10 p.m. every day except Valentine's Day, when they ring again at midnight for the tradition.
