Maenclochog lies south of the Preseli Mountains, about one mile southeast of Rosebush on the B4313 Narberth to Fishguard road.

[2][3] A local tale reports that there were stones near Ffynnon Fair ("Mary's Well"), to the south of the village, which rang like bells when struck, but these were blown up by treasure-hunters, in the mistaken belief that they concealed a golden treasure.

This theory is supported by the fact that there was Irish migration to Pembrokeshire in the early Middle Ages, as attested to by the 5th or 6th century Ogham stones found in the locality and elsewhere, and certainly the name suits the topography of the area.

The tunnel just outside Maenclochog was used during World War 2 as a bomb-test site for Barnes Wallis, creator of the bouncing bomb.

In the centre of the village is St Mary's church (Welsh: Eglwys Fair), the park and the green on a small road island.

[11] Ysgol Gymunedol Maenclochog[12] is a Welsh-medium primary school built in 1878; it has roughly 100 pupils ranging from age 3 to 11.
