The communities of Marloes and St Brides are situated west of Haverfordwest on a peninsula on the southern shore of St Brides Bay, within the Pembrokeshire Coast National Park.
Marloes & St Brides are surrounded to the north, west and south by sea, with 10 km of beautiful cliff scenery and beaches such as St Brides Haven and Marloes Sands. The parish also includes the island of Skomer, famous for it large populations of seabirds, including Puffins and Manx Shearwaters. Skomer is accessed by boat from Martin's Haven at the tip of the peninsula. Also included are the small islands of Grassholm (home to a large population of Gannets) and Gateholm.
Marloes itself is a small village perched in the high land in the centre of the Marloes peninsula. It is usually pronounced “Mar-lows” but locals often say "Marlas". The name appears to derive from Old Welsh mail = "bare" and ros = "moor" or "promontory", identical to Melrose in Scotland. The residents of Marloes have traditionally been known as “GULLS” - based on the the tradition of harvesting gulls eggs from Skomer.
In the centre of Marloes is the well known landmark - the Clock Tower. This was built in 1904 by members of the Pembrokeshire Liberal Association as a memorial to the 4th Baron Kensington.
St Brides comprises a number of scattered farms and dwellings, with a delightful old church situated behind St Brides Haven, a sandy cove on the north coast of the peninsula. The picturesque St Brides Castle (a Holiday Property Bond property) overlooks the haven.
