The oldest TDCJ unit and the site of all Texas state executions. Located in Huntsville, Walker County.

Overview

The Huntsville Unit is commonly called “The Walls.” It is the oldest prison in the Texas system and the site of all state executions. The unit also serves release functions for some male prisoners and remains one of the most historically significant facilities in TDCJ.

Because of its role in executions, releases, and system administration, the unit is more visible in public records and media coverage than a typical prison.

Visiting Basics

Weekend visitation follows standard TDCJ scheduling rules unless the unit posts a change.

  • Visits are usually scheduled through the TDCJ Online Visitation Portal.
  • Standard visiting days are Saturday and Sunday.
  • Visits are subject to cancellation, counts, and other operational restrictions.

What Maximum Security Means Here

The Huntsville Unit frontmatter classifies the site as maximum security, but the unit also houses transient and release-related populations. Visitors should expect close supervision and limited flexibility at check-in.

Directions From Houston

Huntsville is roughly 70 miles north of Houston.

  • Take I-45 North toward Huntsville.
  • Exit into downtown Huntsville and follow local streets toward 12th Street.
  • The unit is inside the city rather than on a remote farm road, which makes the final approach simpler than many TDCJ sites.

Parking and Entry

  • Visitor parking is available near the unit.
  • Standard TDCJ item restrictions apply.
  • Coins for vending are permitted within TDCJ limits; larger personal items remain in the vehicle.

Nearby Services

Because the unit is in Huntsville rather than in a rural unincorporated area, nearby services are easier to find than at many Texas prisons.

  • Gas stations are available along I-45 and inside Huntsville.
  • Restaurants, chain food options, and coffee shops are available in town.
  • Lodging is available along the interstate corridor for visitors traveling long distances.
