The Story
In 1902, entrepreneur A. J. Zilker built an aerial cable conveyor whose towers carried buckets of clay from pits south of the Colorado River up to a brickmaking plant in early-20th-century Austin. Brick was the building material of a fast-growing Texas capital, and Zilker's works fed that boom until the Butler Brick Company leased and expanded the operation around 1912. This surviving bucket tower is a rare relic of the machinery that once moved raw earth across the river into the walls of a city.
Why it matters
It preserves the industrial infrastructure behind an ordinary American building boom, reminding us that cities like Austin were literally built from the clay of their own riverbanks.
The story behind this marker
AI contextThe era
In the early twentieth century, Austin was a Texas capital on the rise, and a rising city needs building material. That meant brick — for storefronts, houses, public buildings, and the walls of a growing town. And brick, in turn, meant clay, dug straight out of the earth and fired into something durable.
This was the Progressive and early modern era, a time when clever machinery was transforming how raw materials moved. Rather than haul heavy clay by wagon, an enterprising builder could rig up mechanical systems to do the lifting — including aerial conveyors that carried buckets of material through the air on cables, over obstacles that would have slowed a cart to a crawl.
The great obstacle here was the Colorado River. The clay lay in pits on the south side of the water, and the brickmaking plant stood nearby on the other. Bridging that gap efficiently was the whole engineering problem this tower helped solve.
People & events
The figure at the center of the story is A. J. Zilker, an Austin entrepreneur whose name still carries weight in the city. In 1902 he installed the cable conveyor system that this tower — one of three — was built to support, sending buckets of clay from the pits south of the river up to a brickmaking facility nearby.
It was an ingenious operation: an overhead line of buckets, steadily carrying raw earth across the landscape so the plant could keep turning it into brick. The towers were the backbone of that system, holding the cable aloft along its route.
In 1912 the Butler Brick Company entered the picture, leasing Zilker's plant. The inscription breaks off mid-sentence as it begins to describe what came next, so the fuller account of the Butler years is left, quite literally, unfinished on the marker — but the handoff from Zilker's original works to the Butler operation marks the next chapter in the site's industrial life.
Its place in the American story
This tower is a rare survivor of the unglamorous machinery that built American cities. We tend to remember the finished buildings and forget the systems that fed them raw material — the pits, the conveyors, the kilns. Here, one of those systems left a piece of itself standing.
It tells a truth that is easy to overlook: cities like Austin were, in a very literal sense, built out of the ground beneath and beside them. The clay of the riverbanks became the brick of the walls, and infrastructure like this cable conveyor was what moved earth into architecture at the scale a booming town required.
That is why a single tower matters. It stands for an entire era of local industry — the moment when a growing American capital learned to mine, move, and remake its own landscape into the fabric of the city.
If you visit
Look for the tower as an artifact of engineering, not decoration. Once you know its job — holding up a cable that ferried buckets of clay through the air — the whole vanished system starts to take shape in your imagination: the pits on one side, the plant nearby, and the steady overhead procession of buckets in between.
Let the Colorado River anchor the scene. Picture clay being lifted from pits on the south side and carried across toward the brickworks, and you will understand at a glance why anyone bothered to build cable towers in the first place.
For visitors curious about how Austin actually got built, this is a small but evocative stop, tied to the enterprising A. J. Zilker, whose name Austinites will recognize. Give it a look, imagine the buckets swinging overhead, and you will never see the city's older brick walls quite the same way again.

Site of John Bremond & Company
Austin, TX
New York native John Bremond opened a dry goods store here as early as 1847, and by the 1860s he and his sons had built John Bremond & Company into a cornerstone of Austin commerce. The family helped launch the city's first hook-and-ladder company and championed the railroad that reached Austin in 1871; a back room even birthed what became the State National Bank. The firm later roasted and shipped its own coffee statewide before closing in 1967, its old limestone building reputedly Austin's oldest commercial structure at its 1979 demolition.
Sixth Street
Austin, TX
Laid out as Pecan Street on Edwin Waller's 1839 plan for the new capital, this thoroughfare drew a diverse population and grew into a commercial heart of nineteenth-century Austin. Its flat ground and safe distance from the flood-prone Colorado River made it ideal for shops, saloons, stables, and lumber yards, often with owners living above their businesses. Renamed Sixth Street in 1884, it accumulated Austin's largest concentration of Victorian commercial architecture, and restoration efforts begun in the 1960s revived the district.
Texas State Capitol
Austin, TX
After an earlier 1850s limestone statehouse proved structurally unsound and then burned in 1881, Texas financed a grand replacement by setting aside three million acres of public land. Detroit architect E. E. Myers won a national competition, and from 1882 crews raised a Renaissance Revival capitol of Texas Sunset Red granite hauled in on rail lines built for the job. When the Goddess of Liberty was hoisted atop the dome in 1888, the building stood more than fourteen feet taller than the U.S. Capitol.
Texas Highway Department
Austin, TX
Created on April 4, 1917, as automobiles were revolutionizing travel and farmers demanded all-weather roads to market, the Texas Highway Department set out to organize a statewide system backed by federal matching funds. A one-cent gas tax after 1923 and New Deal relief funds during the Depression fueled massive road building, and in 1933 the agency completed this headquarters building. From here DeWitt C. Greer led the department for decades; the building was later named in his honor.
