Over the next two hundred years, Dunkale was divided into smaller parcels, and by the mid-1800's, the property that is now Millstad was a working farm. The Great Hall dates from this period, originally a bank barn with thick stone walls, a trussed roof, narrow slit windows, and the cast-iron sounding bell.

By 1908, the property had ceased to be a working farm and became instead a place for children's education and recreation. One acre nearest to Whitaker Mill Road housed the Dunkale School, a one-room schoolhouse that in 1919 boasted 20 students. The Children's Fresh Air Society of Baltimore established a camp on the remaining acreage, offering city children a summer holiday in the countryside. During its years as a camp, the property featured a creek-fed swimming pool, nature trails, camp cabins (the boys' cabins are now extensions of the gymnasium), a theater (now the dance studio), baseball fields, and a basketball court.

In 1977, the Hegstad family purchased the property, and they continue to maintain this very special place. Today the camp is known for weddings and receptions, music, dance, sports retreats, company picnics, concerts, and……your next historic event.
