The Adams Shakespearean Theatre, dedicated in 1977, was designed by Douglas N. Cook, Festival producing artistic director, along with Max Anderson of the Utah State Building Board, and is patterned after drawings and research of sixteenth century Tudor stages. Experts say it is one of a few theatres that probably comes close to the design of the Globe Theatre in which Shakespeare's plays were originally produced. It is so authentic, in fact, that the British Broadcasting Company filmed part of its Shakespeare series there. It is named for Grace Adams Tanner, a major benefactor of the Festival, and her parents, Thomas D. and Luella R. Adams. It seats 819, plus 66 gallery-bench or standing-room seats.
The Randall L. Jones Theatre, dedicated in 1989, was designed by the firm of Fowler, Ferguson, Kingston, and Ruben, with theatrical design by the California firm of Landry and Bogan, as well as Cameron Harvey, Festival producing artistic director. It was built at a cost of $5.5 million, to expand the Festival's offerings, especially in the area of world classics, and was featured in the August 1990 edition of Architecture magazine. The theatre is named after a Cedar City native known as the father of tourism in southern Utah. It seats 769.
