The Lackawanna County Courthouse occupies a 4.7-acre lot bounded by Washington Avenue, Linden Street, Adams Avenue, and Spruce Street in downtown Scranton. The Courthouse is a three-and-one-half-story, rectangular plan, masonry building measuring approximately 100 by 140 feet with a raised basement, hipped roof, and a five-story clock tower. The foundation and walls are finished with rough-cut, coursed, local stone and the roof is sheathed with tile shingles while the water table, stringcourses, window sills, lintels, and buttress caps are trimmed with Onondago limestone. The courthouse property includes the stone courthouse, originally built in 1884 in the Romanesque Revival style and enlarged in 1896 with the addition of a third story and the reconstruction of the roof, and the 1924 John Mitchell Monument, sculpted in bronze and granite. The 1924 John Mitchell Monument fronts Adams Avenue southeast of the courthouse. The monument consists of four sections: a heroic-sized bronze statue, a granite monolith containing a niche in the southeast facade, and two low, curved, granite benches flanking either side of the granite monolith. A bronze statue of John Mitchell stands atop a granite block that is inscribed with the words "John Mitchell (1870-1919)."

The Lackawanna County Courthouse and John Mitchell Monument are located in a square surrounded by Washington Avenue, Linden Street, Adams Avenue, and Spruce Street in Scranton. The Courthouse is open during normal business hours.
