The Volunteer Guard of Texas established the camp in 1890, which is now the 375-acre home to the Thirty-Sixth Infantry Division of the Texas Army National Guard. Camp Mabry is the third-oldest active military post in Texas. A series of brick and timber buildings was constructed in 1918 in collaboration with the University of Texas as a school for auto mechanics and was built in barely six months. This headquarters building and the original barracks nearby (Buildings Nos. 10, 11, 14, and 15) are long, two-story brick structures with wood porches arranged along the parade ground. Buildings Nos. 10 and 11 were rehabilitated in 2011 by Bailey Architects. The Texas Military History Museum, Building No. 6 (2009 rehabilitation, Bailey Architects), occupies the original mess hall, and is capable of seating 4,000. Access to Camp Mabry is now by a new security gateway farther west on W. 35th Street, but is still open to the public.
