Bro Machno is a community in Conwy County Borough, in Wales, formed from the former civil parish of Penmachno.

[1] Tŷ Mawr, a 16th-century farmhouse now owned by the National Trust, was the birthplace of William Morgan, who in 1588 first translated the whole Bible into Welsh.

It is the only surviving document issued by one of the Welsh leaders during the revolt, and in it Madog styles himself Prince of Wales, Lord of Snowdonia.

Because of the remoteness, and inaccessibility during bad weather, of Rhiwbach quarry, the workers lived on site, and a small village developed, including a shop and school, in addition to family accommodation and a barracks for single men.

Extensive remains of the village can still be seen, along with the ruins of the engine house which provided the power to haul the slate up the incline to the tramway.
