Mark W. Michael Unit

The Mark W. Michael Unit (MI) is a Texas Department of Criminal Justice men's prison located in unincorporated Anderson County, Texas. The unit is along Farm to Market Road 2054, 4 mi south of Tennessee Colony. The unit, on 20518 acre of land, is co-located with the Beto, Coffield, and Powledge prison units and the Gurney Transfer Unit. The unit is in proximity to Palestine and the Rusk ironworks, and it is in about a one-hour driving distance from Dallas.

The Michael Unit opened in September 1987. Texas officials referred to the facility as "model for the future." Robert Perkinson, author of Texas Tough: The Rise of America's Prison Empire, described Michael as "one of the meanest lockups" in Texas.

Operations
Michael was one of the first prisons to no longer use the "telephone-pole" layout, which has central pickets with dead-end cell blocks extending from them. The telephone-pole layout, while inexpensive to build, is difficult to police without building tenders, convicts paid to police other convicts. Instead Michael uses a modular pod design, which allows for riot control and visual surveillance. Most pods have double-bunk, reinforced concrete cells with security features such as slit windows and bolted-down metal toilets. Some pods have dormitories. Michael was one of several new prisons to have the ability to have many prisoners in extended lockdowns. State officials said that Michael's features allowing for extended lockdowns of prisoners were modeled on the United States Penitentiary, Marion.
