Located in the Benedictine Center, Our Lady of the Annunciation Chapel, designed by Marcel Breuer and constructed of concrete and North Dakota fieldstone, was completed in 1963 and provides a welcoming setting for prayer with its strength and simplicity. Walls of the split fieldstone are natural on the exterior and painted white on the interior. Breuer’s signature attention to light, shadow, texture, and use of form and space are evident throughout the chapel. The altar, focus of the chapel, and ambo are of polished blue granite. The sanctuary features a reredos of gold-leafed ceramic tile and a blue, cantilevered baldachin over the altar. The chapel seats 500 in its laminated oak stained brown black pews and choir stalls. Floor-to-ceiling windows with fieldstone-shaped stained glass panes, rose-accented on the east and amber on the west, provide a unique visual experience. The 1,641 pipes of the chapel’s Reuter organ are visible in the balcony above the main entrance in keeping with Breuer’s functional style.
A meditation room, the “Mary Shrine” set off by terra-cotta flue tiles near the chapel’s main entrance, contains the Gerald Bonnette (Newport, Minnesota) sculpture "Mary, Prototype of Every Witnessing Christian." The statue is of laminated red oak and weighs about 600 pounds.
Our Lady of the Annunciation Chapel was consecrated on May 13, 1963, indicated by the twelve granite wall candleholders marked with a cross.
The Eucharistic liturgy is celebrated in Our Lady of the Annunciation Chapel on special occasions such as Ash Wednesday, baccalaureate, and at the beginning of the academic year. The music department hosts "Christmas at Mary" as well as other band, choir, and chamber group performances in the chapel. An outdoor fountain of Minnesota granite marking the entrance to the foyer of Our Lady of the Annunciation Chapel, is aligned with the bell banner and the chapel’s altar.
