Texas established its first state penitentiary in Huntsville in 1848, twelve years before the Civil War. The Walls Unit — named for the thick stone walls built by convict labor — became the center of the Texas prison system and the site of all state executions. The first legal execution in Texas took place in 1819, a hanging administered at the county level; the state took over executions in 1923, the same year electrocution replaced hanging as the method.
Old Sparky went into service at the Walls Unit in February 1924. The chair is built from oak and was manufactured in-house at the prison. Between 1924 and August 1964, 361 people — 360 men and one woman — were executed in it. The executions took place in a room adjacent to death row, which inmates called the death house. Texas switched to lethal injection in 1982; the first lethal injection execution in American history took place at the Walls Unit on December 7, 1982, when Charles Brooks Jr. was executed.
Old Sparky was retired in 1964 and was eventually acquired by the Texas Prison Museum, which opened in its current Huntsville location in 1989. The replica death chamber surrounding the chair is built to the dimensions of the original room at the Walls Unit. The museum also displays the largest collection of shivs — improvised weapons confiscated from inmates — in the country, along with escape equipment, tools used in documented prison breaks, and an extensive archive of inmate artwork.
The Walls Unit itself, less than three miles from the museum, remains an active prison and execution facility. As of 2026, it has carried out more executions than any other facility in the United States. The coexistence of the historical museum and the active execution facility is part of what makes Huntsville an unusual destination in dark tourism.

Cold spotsSense of presenceUnease
The Texas Prison Museum does not market itself as a haunted attraction, and the staff is generally cautious about discussing paranormal reports in an institutional context. What gets discussed among visitors and documented in ghost enthusiast accounts is more atmospheric than dramatic: a persistent discomfort in the room with Old Sparky, described variously as cold spots and a sense of occupancy in a room with no one in it.
The chair itself has a particular quality that visitors describe differently but consistently — an object used in 361 state killings over four decades, polished and maintained, sitting under institutional lighting in a room that replicates the last physical space hundreds of men occupied before their deaths. Whether any of that history has left something detectable is a question visitors tend to arrive with and leave still holding.
Huntsville's broader environment adds to the register. The Walls Unit is an active prison; executions by lethal injection continue there. The town has a population that has lived alongside the prison system for 175 years and includes many people who have worked in corrections. Local accounts of the Walls Unit grounds involve the usual suite of prison ghost claims — figures in windows, sounds from empty cell blocks — but the museum draws the dark tourism crowd specifically because the primary artifact is verifiable, documented, and sitting in the room.
The Texas Observer's profile of the museum noted that the annual visitor count of approximately 34,000 skews toward people who come specifically because the subject matter is uncomfortable. The question of what, if anything, 361 executions leave behind in the object used to carry them out is one that the museum implicitly raises and declines to answer.
