Provo and the entire region are probably best known as the home of BYU. The university was established as the Brigham Young Academy in 1875, with a mandate to combine teaching about the sacred and the secular. It has grown into one of the world's largest church-affiliated universities, and still reflects the conservative nature of the Mormon Church. Students must adhere to a strict dress and honor code, and refrain from alcohol, tobacco, coffee, and tea. BYU is known for its large variety of quality undergraduate and graduate programs, is a considerable force in regional athletics. Heading up BYU attractions is a quartet of museums. A free guided university tour is offered weekdays on the hour, and reservations are recommended.
