Historical Information
Ysgol Mynydd Isa has a long proud history having originated in a tiny lean-to built in the late 1800’s on the rear of the now demolished Calvanistic Methodist Chapel on Mold Road, Mynydd Isa just up from Chapel Street.
In 1906, Flintshire County Council built a new primary school in Bryn-y-Baal. The original building on this site survives today much expanded and changing its name over the years – It became Mynydd Isa Junior School when a separate infants school as Mynydd Isa expanded in the early 1970’s. For many years the sign outside the school proclaimed ‘Flintshire County Council Mynydd Isa Primary School’ despite Flintshire becoming part of Clwyd and it was well into the ‘reign’ of the new Flintshire Council before it was replaced (and preserved by the school).
In 2011 the infants school was combined with the junior school and once again became a single school, now known as Ysgol Mynydd Isa.
