The Casas Reales

San Antonio, Bexar County, Texas

Marker Inscription

On site chosen July 2, 1731, for "government houses" by people of San Fernando de Bexar, including newly-arrived settlers from the Canary Islands. Structure, erected 1742, had to be rebuilt in 1779 by Don Jose Antonio Curbelo, alcalde of the Villa San Fernando de Bexar. A jail was erected to the south in 1783. From commanding position of Casas Reales on Main Plaza were read official proclamations, to the roll of drums. A noted visitor in 1807 was Lt. Zebulon M. Pike, freed after arrest on upper Rio Grande while exploring Louisiana Purchase for the United States. Briefly in 1813 over the Cases Reales flew the green flag of the rebel Republican Army of the North, formed to free Mexico from Spain's rule. Aided by the Baron de Bastrop, Moses Austin in December 1820 initiated the Anglo-American colonization of Texas by filing his petition and plans with the governor and cabildo (council) in Casas Reales. Santa Anna arrived here February 23, 1836, to press the siege of the Alamo. The bloody "Council House Fight" between Texian leaders and Comanche chiefs occurred here on March 19, 1840. The building served as municipal headquarters under Spanish, Mexican, Republic of Texas, and American regimes, but were vacated in 1850 by the city. (1971)

The Story

Chosen in 1731 by the Canary Islander settlers of San Fernando de Bexar, the Casas Reales served for more than a century as the seat of government on San Antonio's Main Plaza. From its steps, officials proclaimed the news of empires and republics to the roll of drums; Zebulon Pike passed through in 1807, the green flag of Mexican rebellion flew over it in 1813, and Moses Austin filed his colonization petition there in 1820. Santa Anna made it his headquarters during the siege of the Alamo in 1836, and four years later the deadly Council House Fight erupted here between Texan officials and Comanche leaders.

Why it matters

Few buildings witnessed so much of Texas history in one spot — Spanish, Mexican, Republic, and American rule all governed from this plaza, where the collision of empires, settlers, and the Comanche played out.

The story behind this marker

AI context

The era

To stand on San Antonio's Main Plaza is to stand at one of the oldest continuously governed spots in Texas. The story begins in 1731, when the settlers of San Fernando de Bexar — including a group newly arrived from the Canary Islands, sent by the Spanish crown to anchor the frontier — chose this site for their "government houses," the Casas Reales. It was July 2 of that year, and the choice fixed the seat of civil authority in a place it would hold for more than a century.

The structure raised in 1742 had to be rebuilt in 1779, and a jail rose to the south in 1783. This was the far northern edge of Spain's American empire, a fortified town of missions and plazas holding the line against rival powers and against the Native nations whose lands surrounded it. The Casas Reales sat at the civic heart of it all: from its commanding position on the plaza, officials read proclamations aloud to the roll of drums, the way a frontier town learned the will of a distant crown.

Over the following decades the flags above this plaza would change again and again, and the Casas Reales would witness every turn.

People & events

The building's guest list reads like a roll call of the forces that shaped Texas. In 1807 Lieutenant Zebulon M. Pike passed through — an American army officer who had been arrested on the upper Rio Grande while exploring the newly purchased Louisiana Territory for the United States, and then released. His visit was an early brush between the Spanish borderlands and the young American republic pressing westward.

Events accelerated from there. Briefly in 1813 the green flag of the Republican Army of the North flew over the Casas Reales, raised by rebels seeking to free Mexico from Spanish rule. In December 1820, aided by the Baron de Bastrop, Moses Austin filed his petition and plans here with the governor and the cabildo, the town council — the act that opened the door to Anglo-American colonization of Texas. A single building thus stood at the hinge between Spanish Texas and the flood of settlement that would remake it.

Then came the most dramatic days of all. On February 23, 1836, Antonio López de Santa Anna arrived here to press the siege of the Alamo, making this plaza the command post of a campaign that would echo through Texas memory. Four years later, on March 19, 1840, the same ground saw the bloody Council House Fight, a catastrophic breakdown of negotiations between Texian officials and Comanche chiefs that ended in violence and shaped relations on the frontier for years. Through all of it, the Casas Reales served as municipal headquarters under Spanish, Mexican, Republic of Texas, and American rule.

Its place in the American story

Few places in the United States concentrate so much of a region's history into a single footprint. The Casas Reales governed under four sovereign flags — Spain, Mexico, the Republic of Texas, and the United States — and each transition was not an abstraction but a change in who read the proclamations from these steps. To trace this one building is to trace the whole contested making of the American Southwest.

That larger story is one of collision: the northward reach of the Spanish empire, the birth of an independent Mexico, the arrival of Anglo-American colonists that Moses Austin's petition set in motion, and the enduring power of the Comanche and other Native nations whose presence the Council House Fight makes impossible to forget. The plaza was where these forces met, negotiated, and clashed.

Most buildings that matter to American history witnessed a single great moment. This one witnessed a succession of them, in the same spot, across more than a century — which is why the ground itself, not any surviving wall, is the monument. The city vacated the old government houses in 1850, but the plaza remained the civic center it had been since 1731.

If you visit

Main Plaza in San Antonio is still a living civic square, and that continuity is the whole experience. The Casas Reales themselves are long gone — vacated in 1850 — so what you are really visiting is the ground, and the trick is to let the marker repopulate it. Stand where proclamations were once read to the roll of drums and try to hear them.

San Antonio wears its layered past openly, and this plaza is its oldest layer. The famous mission a short distance away draws the crowds, but the marker here points you to the parallel civil story — the governing, petitioning, and negotiating that happened on the plaza while soldiers fought elsewhere. Knowing that Santa Anna directed the siege from this very place changes how the whole downtown feels.

Give yourself a moment to hold the sweep of it: Canary Islanders in 1731, an American explorer in 1807, a rebel flag in 1813, Moses Austin's petition in 1820, and the terrible Council House Fight of 1840, all on one patch of earth. No hours, no ticket, no single wall to photograph — just a plaza that has been the center of things for nearly three centuries, and a plaque that tells you why.

250th Anniversary of the Founding of San Antonio

San Antonio, TX

Spaniards first explored and named this area in 1691, and colonial settlement took hold in May 1718 with the founding of Mission San Antonio de Valero—later known as the Alamo—beside the presidio San Antonio de Béxar. Renamed San Fernando de Béxar in 1731 when it became Texas's first municipality, the settlement kept the name "San Antonio" and served as the province's capital from 1772 to 1824. The city has lived under nine governments, a heritage celebrated at HemisFair '68 on its 250th anniversary.

San Antonio, TX

A South Carolinian who reached San Antonio in 1835, Samuel Maverick guided Ben Milam and the Texian force in the first assault on the town, signed the Texas Declaration of Independence in 1836, and endured seven months as a prisoner in Mexico's Perote castle. Twice mayor of San Antonio, he rode with Jack Hays' Minute Men against Comanche raids and later helped negotiate the bloodless surrender of federal forts in 1861. His habit of leaving cattle unbranded gave English the word 'maverick.'

The Bullis House

San Antonio, TX

This Neo-Classical Revival residence was completed in 1909 for Gen. John Lapham Bullis, a New Yorker who spent much of his career on the Southwestern frontier. In 1873 Bullis took command of a company of Seminole Scouts whose skill at tracking raiders on the Texas border drew national attention. He lived in the house, designed by San Antonio architect Harvey Page, until his death in 1911; nearby Camp Bullis bears his name.
