The Pierce-Klingle House, or Klingle Mansion, is situated on Williamsburg Lane above the west bank of Rock Creek less than half a mile below Pierce Mill. Joshua Pierce, a son of the mill builder, built the house in 1823 and enlarged it by an addition on the west side 20 years later. The Pennsylvania Dutch-style structure is of blue and gray granite and encloses 10 rooms within its three stories. A two-story stone and wood frame barn stands to the east, and a utility house and potting shed flank the rear.
