The Tagart Memorial Chapel was dedicated on May 5, 1899 and named for Samuel Tagart, President of the Board of Trustees when the school was founded. In 1978, McDonogh's famous 48 bell carillon was donated by Mr. and Mrs. H. Beale Rollins. Over the years, the chapel has been home to hundreds of ceremonies and gatherings, such as Baccalaureate and the Junior Pin Ceremony as well as choral and music concerts, and class meetings. In addition, weddings and memorial services are held in the chapel.
