An 1854 engraving shows a 3½-story gabled mill, 195 by 45 feet, with a small cupola. Today the basement and first story remain, built of random rubble granite with heavily parged joints and cut granite lintels. The stucco-covered office is a three-bay, gable-front building with a trabeated granite doorway. Chace ran the business until the Mount Hope Mill Company took over in 1867. The mill shut down in 1878, and in 1880 it reopened as Conanicut Mills, which operated until 1926 and by 1920 had 29,408 spindles and 776 broad looms. Water power from a canal supplemented steam and electricity. Local historians attribute the ruined state to time rather than fire. The site is considered the oldest remaining textile manufactory in the city and the only surviving example of this early mill period.","period_of_significance":null,"architect_builder":"Oliver Chace (builder of the mill)","architectural_style":"Greek Revival (office building); random rubble granite mill","criteria":["A","C"],"status_note":"Mill is in ruins, covered with vines; abandoned for over fifty years.
