Campus TMI has moved three times, each time relocating to the edge of an expanding city. The first campus was on Government Hill, next to Fort Sam Houston; the second was in Alamo Heights; and the current campus, dating from 1989, is in far northwest San Antonio, on the edge of the Texas Hill Country. The campus is modern in architecture and built almost entirely from local limestone. Features of the campus include: The Frost Athletic Center is a large gym, incorporating two basketball/volleyball courts, two squash courts, a rifle range and a natatorium with a half-olympic length pool, as well as the school infirmary and offices for athletic and JROTC staff. Coates Hall, the main academic building, incorporates most of the classrooms, labs and faculty offices. It is built around two courtyard gardens with open-air hallways. A small greenhouse built alongside Coates hall is used for botany lessons. The All Saints' Chapel is a 500-seat modern chapel, used for daily service of Morning Prayer and for Eucharistic services on the first Wednesday of every month as well as for quarterly school Evensongs, choral concerts and the annual baccalaureate Mass. The chapel, designed by alumnus Chris Carson of Ford, Powell & Carson, was recognized as one of the best religious buildings of 2009 by the Interfaith Forum on Religion, Art and Architecture, a knowledge community of the American Institute of Architects. The chapel organ is a two manual, 18 voice Schoenstein & Co. opus. The Johnston Amphitheatre is used for graduation and for some school assemblies during fair weather. Ayres Hall incorporates administrative offices, a black box theatre, kitchens, refectory, and library, which houses music, archived newspapers and magazines for much of the 20th century, as well as 17,000 books, including a rare books conservation section. The Butterfly Garden was built and is maintained by the environmental science class. The Roger Kramer Observatory and Virgil Espino Telescope is used for astronomy classes. The Orchard has apple and plum trees. Houses and Dormitories house boarding students and some residential faculty, while the headmaster, chaplain, school physician and other resident faculty live in detached houses. Walker Innovation Center is TMI's newest addition to campus. On
