Oak Glen Schoolhouse Museum and Park

The original wooden schoolhouse (circa 1889) was replaced by this two-story stone structure in 1927, and it continued operating as a school until 1965. Today, it's a museum with vintage desks, blackboards, textbooks, a 48-star American flag, and artifacts dating from the 1880s. Outside the museum is a playground and picnic area.
