Origin of the name
Mynachlog-ddu and the surrounding Preselis are rich in prehistoric remains. It is one of the possible sites of the Battle of Mynydd Carn in 1081. By c.1100 it was under the control of the Normans. Much has been unenclosed moorland since mediaeval times, with few houses. The village developed as housing for slate quarry workers and there has been a chapel in the village since 1794.
The population of the parish in 1821 was 447.
Carn Menyn is presumed to be the source of the bluestones used in the inner circle of Stonehenge. In 2000/2001 a project was established to try to transport a piece of bluestone from the village to Stonehenge. The project ended when the stone sank in the sea. It was lifted out a few months after, but the project was never resumed. A comedy based on the idea of a campaign to have the bluestones returned Bringing Back the Bluestones premiered in Pembrokeshire.
The poet Waldo Williams was a pupil at the primary school (where his father was headteacher) between 1911 and 1915, where he learned to speak Welsh.
