In 1937 Professor J.B. Whelehan, the then Chief Scout, together with the National Executive Board of CBSI (later Scouting Ireland (CSI)), decided to purchase a campsite. Many venues were suggested, but eventually two options remained. One was Santry Demesne, part of which is now the Morton Stadium for athletics, near Dublin Airport, and the other was Larch Hill. The decision fell to the casting vote of Prof. Whelehan, whose foresight saw that the Santry site would become part of the city far more quickly than its south-side counterpart.
