Camp Mabry

Camp Mabry (ICAO: KATT) is a military installation in Austin, Texas that houses the headquarters of the Texas Military Forces. Its original 90 acre site, three miles (5 km) northwest of downtown west of Mopac Expressway, was deeded from the city to the state in 1892. It was named for Brigadier General Woodford H. Mabry the Adjutant General of Texas from January 23, 1891 to May 4, 1898. The camp was added to the National Register of Historic Places in 1996.

Camp Mabry is the third-oldest active military installation in Texas behind Fort Sam Houston and Fort Bliss. Camp Mabry currently houses the office of the Adjutant General, as well as the headquarters of the Texas Army National Guard, the Texas Air National Guard, and the Texas State Guard. Other facilities include the 136th Regional Training Institute, state Combined Support Maintenance Shops, the armory of the 36th Infantry Division headquarters, a clinic, a parachute packing and storage facility, and additional storage buildings. In 1992 the Texas Military Forces Museum opened on the site.

For many years at the turn of the 20th century, the camp was home to annual encampments by the Texas state militia, who hosted reenactments and demonstrations for the people of Austin. Grandstands were built on the site, and further improvements to the site were funded by paid admissions to the events. By 1911, the camp had expanded to more than 385 acre. The first permanent building onsite, an arsenal, was completed in 1915 and allowed military weaponry and equipment to be moved out of storage in the capitol building.

Prior to the attacks on September 11, 2001, Camp Mabry's mile-long track that sits adjacent to Mopac was a popular destination for walkers and joggers, and the field within it was used by many youth sports teams. The track and field are still available for public use. For access to the track and museum, adult visitors must present a state or federal ID at the gate.

Camp Mabry has also operated an ICAO recognized weather station since 1898.
