Roch Castle (Welsh: Castell y Garn) is a 12th-century castle, located at Roch near Haverfordwest, Wales. Built by Norman knight Adam de Rupe in the second half of the 12th century, probably on the site of an earlier wooden structure. Roche is the usual French word for rock, while rupestre signifies a plant growing among rocks. The Castle was purchased in 2008 by the Griffiths-Roch Foundation who restored it for operation by the Retreats Group as a vacation home and corporate retreat.
