Old Hidalgo
The Old Hidalgo Jail Also Carried a Newspaper Chapter
The Old Hidalgo County Jail packs a lot of border history into one small brick building. The Texas Historical Commission says S. W. Brooks built the two-story jail in 1886, the same builder tied to the nearby courthouse, using handmade brick with a corbeled cornice along the roofline.
It went up during a rough stretch, when outlaw raids still reached the lower river. The marker says the jail served the county until 1908, when the seat of government moved to Chapin, now Edinburg. In its later years it did double duty: The Hidalgo Advance newspaper was published in the building from 1904 to 1908.
Law, county government, border-era unrest, and early local media all share the same square here. Standing in front of the old jail, a visitor can read most of Old Hidalgo's first chapter off one building.
