Alamo Low Barracks and Main Gateway
San Antonio, Bexar County, Texas
Marker Inscription
Mission San Antonio de Valero, established nearby in 1718, was relocated here in 1724. By 1762, the Mission Plaza was enclosed by thick stone and adobe walls. The 11 x 14-foot main gateway was located at this site along the south wall. In 1803 Spanish cavalry from San Carlos de Parras del Alamo, Mexico, occupied the secularized mission and built one-story (low) barracks inside the south wall on each side of the main gateway. The Alamo, as the complex came to be known, was occupied in 1835 by Mexican soldiers led by Gen. Cos. They fortified the main gateway with artillery pieces and a defensive lunette, a semi-circular enclosure with deep trenches. In December 1835, Texas patriots captured the Alamo, but by Feb. 23, 1836, were under siege by an armed force led by Gen. Santa Anna. Couriers departed the Alamo through the main gateway during the siege. On March 6 Mexican troops breached the main gateway and retook the Alamo. After the assault, some Mexican military observers and local residents stated that Col. James Bowie and others died in the low barracks. The low barracks and main gateway were leveled in 1871, melding Valero Plaza on the south with the Alamo's plaza to create an open space. (1996)

The Story
Mission San Antonio de Valero, founded in 1718 and relocated to this area in 1724, was ringed by thick stone and adobe walls by the 1760s, with its main gateway set in the south wall. After Spanish cavalry occupied the secularized mission in the early 1800s, the complex became known as the Alamo. During the famous 1836 siege, couriers slipped out through this gateway before Santa Anna's troops breached it on March 6, and some accounts place James Bowie's death in the adjacent low barracks.
Why it matters
This ground marks the threshold of the Alamo itself, where the defenders' last stand became a defining symbol in the story of Texas independence.

Alamo Cenotaph
San Antonio, TX
This soaring cenotaph honors the defenders who died at the Alamo on March 6, 1836, in the fight for Texas independence. Rather than marking a grave, it stands as an empty tomb, a symbol raised so that the sacrifice made in that mission-turned-fortress would not be forgotten. Its inscription casts the fallen as men who chose neither surrender nor retreat.
John W. Smith
San Antonio, TX
A North Carolina native who drifted west through Illinois and Missouri, John W. Smith came to Texas with Green DeWitt in 1826 and settled in San Antonio, where he became a leading merchant and political figure. He fought in the opening "affair at Gonzales," the storming of Bexar, and the siege of the Alamo, from which he served as a courier, and later at the Battle of the Salado. Smith became San Antonio's first mayor in 1837, held numerous offices, and served the Republic as a senator until his death in 1845.
El Quartel (El Cuartel)
San Antonio, TX
Built in 1810 as a military barracks in San Antonio de Béxar, El Quartel became a flashpoint in the struggle over Spanish rule. Here in January 1811 Juan Bautista de las Casas raised forces to arrest the royal governor in Texas's first overthrow of Spanish authority, only for Juan Zambrano to muster a counter-revolt that restored the crown weeks later. The barracks were apparently destroyed during the Texas Revolution, when defenders chose instead to make their stand at the Alamo.
Site of de la Garza House, Gardens and Mint
San Antonio, TX
Built in 1734 for prominent Bexar citizens Geronimo and Javiera Cantu de la Garza, this block-long Spanish colonial compound had limestone walls three feet thick and lush gardens. Generations later, José Antonio de la Garza used its vault to safeguard merchants' valuables and, granted royal permission in 1818, minted the small coins called 'jolas'—making the home likely the first mint in Texas. During the 1835 Siege of Bexar, Ben Milam's troops battled two days to seize the fortress-like compound as their headquarters, and Milam died taking the city.
