Dallam County Courthouse © 1998 by Sylvia Renick

Ten years later, when the Rock Island Railroad built a line through the County, the new town of Dalhart was established where the Rock Island, Fort Worth and Denver City Railroad lines crossed. The County Commissioners voted to move the County Seat to Dalhart in 1903, and, in May of 1903 an election was held to approve bonds for a Courthouse in Dalhart.

County government soon outgrew the 1903 building and, in 1922, the voters approved more bonds for a new Courthouse. Designed by Smith and Townes, the classical revival structure was completed in 1923. Built of brick, with cast stone detailing, the Courthouse continues to serve the citizens of Dallam County to this day.
