Although the dyke passed directly through Bronygarth, the area remained strongly Welsh in culture, customs and language.

Settlements were mainly in the valley, along the banks of the River Ceiriog, but with a small number of farms extending higher up the mountainside.

The name Bronygarth appears in documents as far back as the 12th Century and translates into English as "Breast of the Hill" and is thought to have formed part of a hunting estate.

Opposite the school stood a toll house on the Bronygarth and Wern turnpike road, which connected to the main Cardiff to Chester highway at Pontfaen.

Also opposite the 'Old school' is a house which was occupied by the headmaster until it was sold privately The area was highly dependent on agriculture but limestone was also quarried.
