Cosheston is a medieval village stretching along the ancient roadway west of Carew; the medieval burgage plots are still evident.

Shipbuilding was once important on the shores of Milford Haven, notably at Jenkins Point and at Whalecwm where ‘The Chemicals’ is an old naphtha factory. Parts of Upton Castle, two miles from the village, date from the 13th century; the castle is now in private ownership, although the extensive woodland gardens are open to the public. There are relics of both world wars in the area, although no trace remains of the sandbag pill-boxes which would have guarded important road junctions in WWII. One of these junctions was Slade Cross, where until recent road alterations took place, a length of railing replaced part of the old hedge; this was to provide a clear view and field of fire for the pill box defenders.
