Pembroke Dock was originally the ancient parish of Pembroke St Mary's in the hundred of Castlemartin, to the north west of the county town, Pembroke St Michael's, and now forms the industrial base on the south bank of the Cleddau estuary, with access to the Irish Sea via Milford Haven.  A bridge across the estuary of the Cleddau connects the A477 to Neyland, in the north.  The parish to the west across the Pembroke River estuary is Pwllcrochan, with Monkton to the south west.  To the east, the ancient parish of Nash separates Pembroke St Mary's from Cosheston and Carew, in the hundred of Castlemartin.
