Site of Old Block House
Austonio, Houston County, Texas
Marker Inscription
Established before 1836 Used by Elisha Clapp and neighboring settlers as a place of defense against the Indians Abandoned about 1844 Erected by the State of Texas 1936
Erected by Texas Historical Commission
The Story
Before Texas won its independence, settlers on this exposed stretch of frontier built a fortified block house as a refuge from raids. Elisha Clapp and his neighbors used the sturdy log structure as a rallying point in times of danger, a common feature of frontier defense in the 1830s and early 1840s. By about 1844, as settlement grew safer and denser, the block house was abandoned.
Why it matters
Frontier block houses embody the precarious first years of Anglo settlement in Texas, when survival depended on mutual defense and the line between wilderness and community was thin.
The story behind this marker
AI contextThe era
In the early 1830s, the land that became Houston County lay at the edge of Anglo settlement in Mexican Texas. American families were moving in, drawn by cheap land, but they were settling in country that Native nations had long used and defended. Relations could be peaceful or violent depending on the time, the place, and the people involved.
The Texas Revolution of 1835–1836 turned Texas into an independent republic, but it did not settle the frontier. The Republic of Texas had little money and a small army, so settlers in exposed areas often had to rely on themselves and their neighbors for protection.
That's where block houses came in. A block house was a sturdy, usually log-built stronghold where nearby families could gather when danger threatened. They were a familiar feature of the American frontier from the colonial era onward, and early Texas communities used them in the same way.
People & events
The marker tells us this block house was established before 1836, making it older than the Republic of Texas itself. Elisha Clapp and neighboring settlers used it as a place of defense against Indian raids. Beyond what the marker records, little is widely known about Clapp himself, and it's best not to fill in details the record doesn't provide.
What we can picture is the pattern. Families lived scattered across their farms, often miles apart. When word came of trouble, they would gather at the block house, bringing children and whatever they could carry, and wait out the danger behind thick walls. The building was a shared lifeline, and keeping it ready was a community effort.
By about 1844 the block house was abandoned. That timing suggests the local frontier had changed. More settlers had arrived, the line of settlement had moved farther west, and the sense of constant threat that justified a fortified refuge had faded here.
Its place in the American story
The Old Block House captures a chapter of the national story that played out again and again as the United States and its neighbors expanded westward: settlers moving onto contested land and building defenses as they went. From the Ohio Valley to Texas, the block house became a symbol of frontier life and of the reliance neighbors placed on one another.
It also reflects the collision between settlers and Native nations. For Indigenous peoples, the arrival of farms and fortifications meant the steady loss of homelands. The raids the settlers feared were part of a much larger conflict over land that shaped Texas and the American West for decades.
Finally, the block house spans a remarkable stretch of Texas history in only a few years. It stood through Mexican rule, the Texas Revolution, and most of the life of the Republic of Texas, which joined the United States in 1845, just after the block house was abandoned.
If you visit
The block house itself is long gone, so this is a place for imagination rather than ruins. Stand by the marker and look out over the East Texas countryside. Try to picture it thinly settled, with scattered cabins and a single strong building where families knew they could run for safety.
The Austonio area is quiet and rural, so treat the marker as a peaceful roadside pause. Be mindful of private land and traffic, and give yourself a moment to consider how different daily life felt when neighbors depended on one another for survival.
The marker fits nicely into a drive through Houston County and the surrounding piney woods, one of the older regions of Anglo-American settlement in Texas. Pair it with other early frontier and Republic-era sites in the area for a day spent tracing Texas from its rough beginnings.

Bucareli
Midway, TX
In 1774 Spanish authorities resettled East Texas colonists—recently uprooted to San Antonio—at a Trinity River crossing, founding the town of Nuestra Señora del Pilar de Bucareli under leader Gil Ybarbo. The community grew to some 345 people with a church, plaza, and wooden houses, but crop failures, Comanche raids, and floods drove the settlers away by 1779. Led again by Ybarbo, they moved east and rebuilt the old town of Nacogdoches.
Crockett
Crockett, TX
Founded in 1837 and named for David Crockett, who had passed through on his way to the Alamo the year before, Crockett grew into a hub of the young Republic of Texas frontier. Its fortified log courthouse sheltered settlers during conflicts with Native peoples, and by the Civil War the town hosted a camp of instruction. As a telegraph and stagecoach station, it tied the surrounding farming and timber country into the wider South.
Fort Boggy
Centerville, TX
Around 1840, pioneer families settling this corner of Leon County lived uneasily beside Kichai and Kickapoo camps. After Christopher C. Staley was killed while hunting in early 1840, the settlers built Fort Boggy—two blockhouses and eleven dwellings—under a company authorized by Texas President Mirabeau B. Lamar and led by Captain Thomas Greer. Some seventy-seven people crowded inside, plagued more by illness than by raids, until the danger eased after Greer himself was killed in an 1841 attack.
Homesite of Samuel Cartmill Hiroms
Austinio, TX
Samuel Cartmill Hiroms was born in 1836 to parents among Stephen F. Austin's 'Old Three Hundred,' the first Anglo-American colonists of Mexican Texas. A schoolteacher and county surveyor, he served in the Confederate Army before moving his family to Houston County and settling the Creek community — later Austinio — in 1878, where he received land for his teaching and helped lead the local Methodist church.
