The Dallas County Courthouse, built in 1892 of red sandstone with rusticated marble accents, is a historic governmental building located at 100 South Houston Street in Dallas, Texas. Also known as the Old Red Courthouse, it became the Old Red Museum, a local history museum, in 2007. In 2021, it was announced that the Old Red Museum would be moving out and the building is being returned into a hall of justice. The Texas Fifth Circuit Court of Appeals is moving into Old Red (2024).[3][4]
