Dist.# 1 Dyar School building served as classroom for the children of the southern portion of Strong, on the west side of Sandy River, until the late 1890s. It was located across from the present-day Ladd farm on the road to Farmington.

After the district system of rural education was abolished, this building was boarded-up and soon fell into disrepair. However, remnants of the building were still visible well into the 1960s.
