Ardtornish Primary SchoolEdit

Ardtornish Primary School is a state government R-7 coeducational school with an enrolment of about 500 students.[3] The original school was built in 1842 on the Lower North East Road in Hope Valley, and named after Ardtornish Castle in Scotland. In 1980 the school moved to its current site in St Agnes. An extensive history can be found on the School's website[4] along with a slightly shorter version "for younger readers".[5]
