Some 250 students once squeezed into the ten oak-wain-scoted classrooms of this sturdy sandstone structure. This Italianate landmark served as the grade school until 1901, when Clark Elementary School opened nearby at 142 Lawrence Street. After Clark opened, the older school became the high school until its 1966 closing. Then the Gilpin County Historical Society converted the structure, which had been condemned because of a broken boiler, to a museum. Clark School, a sophisticated building with ornate brick-work, dignified Beaux-Arts touches, and a well-preserved interior, is now an annex of the county courthouse.
