Camp Constantin is the flagship campground for Circle 10. Located on 385 acres (1.6 km2) on the shores of Possum Kingdom Lake near Mineral Wells, Texas and containing 15 campsites Constantin acts as both a regular camp open to Boy Scouts from all areas and as Circle 10's largest and longest running summer camp hosting roughly 2,800 Scouts during the 7 weeks it's open during the summer. Constantin was acquired by the Boy Scouts in 1946 when Eugene Constantin donated it, after the death of his son in World War II, to the group that he decided best served the needs, morals, and values of young men. The camp recently celebrated its 60th birthday and regularly plays host to International scouts, most notably Scouting Ireland.
