Also known as the Campanile, this 175-foot structure was built in 1923 and dedicated in 1926 as a memorial to Louisianians who died in WWI. On the rotunda walls are bronze plaques bearing the names of those to whom the Tower is dedicated. The Memorial Tower also houses the permanent collections of the LSU Museum of Art. Chimes ring every quarter hour.

The Cornerstone in front of the tower was excavated from the ruins of Louisiana State Seminary of Learning and Military Academy in Pineville (early LSU) one half describes the history, other half is inscribed with first Board of Supervisors and faculty.
