The parish church of St Michael is well known as the site of the very early Welsh Moccas Monastery, founded by Saint Dubricius in the 6th century,[2] as recorded in the Book of Llandaff.

[3] The church has a notable monument to the de Fresnes family, lords of the manor in the 14th century.

[4] Moccas Court, north of the village, replaced the old manor house which once stood next to the church.

It is a fine Georgian country house, now a hotel, built between 1776 and 1783 for the Cornewall family by the architect Anthony Keck.

"Moch" (pigs) and "rhos" (moorland) combine to give "moch-ros" (soft mutation of RH > R, caused by the preceding word, hence "Mochros" /ˈmɔχrɔs/).
