List of scheduled monuments in Neath Port Talbot facts for kids
Neath Port Talbot County Borough stretches from the south coast of Wales up to the southern edge of the Brecon Beacons. The 93 scheduled monuments include 43 prehistoric sites which include a stone circle, standing stones, burial mounds and chambered tombs. The six Roman sites are all connected to military occupation. There are 18 medieval sites which include abbeys, castles and churches. The 26 post-medieval sites are mostly connected to over 400 years of industrial activity in the area. All of the sites on this list (and the whole of Neath Port Talbot County Borough) are within the historic county of Glamorgan. Five of the sites lie on or cross the border into neighbouring counties, and are included on both lists.
Scheduled monuments have statutory protection. It is illegal to disturb the ground surface or any standing remains. The compilation of the list is undertaken by Cadw Welsh Historic Monuments, which is an executive agency of the National Assembly of Wales. The list of scheduled monuments below is supplied by Cadw with additional material from RCAHMW and Glamorgan-Gwent Archaeological Trust.

Double bank, defining a quadrangular enclosure 25 m across, on a broad ridge SE of Mynydd Margam, near the source of the River Kenfig.

Opinion has swung back and forth on whether this is a natural collection of stone slabs or a neolithic tomb. One explanation could be that the largest stones, the 'capstone' and a supporting slab, may be in situ, but were utilised to create a tomb, possibly covered by a cairn. The site is on a broad ridge of Mynydd Carnlechert, 60m west of the Carn Lechart burial (GM078), further down the slope, and can be seen from there. | Prehistoric (neolithic) |

Also called Cwm-Clais, it may be a 12th-century Welsh castle, built in imitation of Norman mottes. Edward Lhuyd in the 17th century recorded a group of three castles, "Castel y Wiryones", "y Castell" and "Ben y Castell", which may refer to this, along with Plas Baglan (GM358) and Pen-y-Castell (GM098).

Cistercian monastery, once the largest abbey in Wales. Following its dissolution, the Herbert Mansion was built on the Abbot's lodging, and the area then became an industrial site. The substantial ruins were excavated in 1924 and 1934, and taken into public ownership in 1944. It is now in the care of Cadw and open to the public.

Also known as Cryke Chapel and dated to 1470, this grange of nearby Margam Abbey (GM005) is on the hillside of Craig-y-capel. The gable-ends, with window tracery are the principle survivals, and provided a gothic landmark and viewpoint for the 19th-century parkland of Margam Castle.

Founded in 1147, St Mary's Abbey was dissolved in 1536. The nave survives as Margam parish church. The remainder of the abbey complex was acquired by the Mansel, and later the Talbot family, who incorporated the ruins into their parkland and Margam Castle.

Complex arrangement of tramway, canal branch, and canal dock, to link the Waun y Coed Colliery and nearby Ynyscedwyn Ironworks with the canal to Swansea. This required a tramway bridge over the River Tawe, now gone, and wharves and 300 m of canal, now filled in, that linked to the Swansea Canal. Several buildings and foundations of numerous structures remain. | Post-Medieval/ Modern (1828) |

A stone lined section of the Tennant Canal where it runs through the Skewen Cutting, in Neath. Built by William Kirkhouse in 1821, the canal linked the Neath Valley to Swansea docks. The stone lining was to counteract a problem with quicksand. The bridge carried a pre-existing horse-drawn railway, at a time when Britain was the only country in the world with surface railways. | Post-Medieval/ Modern (1821) |

Two blast furnaces and engineering works, with a forge and rolling mill upstream. It was in use from the 1790s to 1885. They were acquired by the Fox and later Price families, who expanded to other sites in the Neath valley. Steam Engine manufacture was an early specialism and shipbuilding were amongst the items produced. Their Quaker principles meant they were against any production of armaments. | Post-Medieval/ Modern (1790s) |

A three-storey watermill, with pit wheel, machinery and stones largely intact, having ceased use in 1940. The dam and leat bring water from the nearby River Cynfig. The site was recorded as a mill in 1291, but the remains are from the early 19th century. | Post-Medieval/ Modern (19th century) |

The most intact of the ironworks on the anthracite coalfield. Built in 1845, and connected to the Swansea Canal by an edge rail wagonway, it may have produced no more than 80 tons of pig iron. Blast furnaces, charging platform, weighbridge and enginehouse all remain after its short-lived operation. | Post-Medieval/ Modern |

Completed in 1825 to provide a wagonway across the Afan valley, it is a 425 yards (389 m) bridge with four huge arches, and is also known as 'Y Bont Fawr' (The Big Bridge). It had a substantial trough to carry water across the valley to power the waterwheels of Cwmafon steelworks. It is now a cycle and pedestrian routeway. (A second viaduct crosses the river Afan to the west, taking a railway up Cwm Pelenna.) | Post-Medieval/ Modern (1825) |

12 km wagonway, with steep inclines to haul coal trucks over the hills from the Blaencregan colliery to the canals of the Neath valley. The construction and operating costs proved unfeasable and both Mr Parsons and his successor were bankrupted by the enterprise. Built between 1839 and 1842 with massive inclines and a steam-powered winding house, it was abandoned in 1852. The scheduled section is on the west side of Cefn Morfudd. | Post-Medieval/ Modern |
GM447 |
| Remains of Lock and Dry Dock at Pantyffynnon | Lock | Ystalyfera | 51°45′05″N 3°48′01″W / 51.7513°N 3.8003°W, SN758073 |
At Lock 17 (or 'sawmill lock') of the Swansea Canal, a dry dock was installed in 1875–6, shortly after the canal was sold to the Great Western Railway. The dry dock was alongside the normal lock, and enabled boats to be floated into place and rested on timber supports, so that the hull could be worked on after the water was emptied. Close by was the quay for Crimea Colliery (GM453) | Post-Medieval/ Modern (1875) |

Dated to early 19th century, before the development of powered fans for ventilation. A brazier within the furnace building created an updraft which sucked old air out of the mine, to be replaced by fresh air via other entrances. This furnace ventilated a drift mine. It is a well-preserved example of early mine ventilation technology. | Post-Medieval/ Modern |

Canal Boat at Aberdulais Basin | Canal Boat | Tonna | 51°40′46″N 3°46′31″W / 51.6794°N 3.7752°W, SS773993 |

River Twrch Aqueduct, Ystalyfera | Aqueduct | Ystalyfera, (also Ystradgynlais), (see also Powys) | 51°46′06″N 3°46′48″W / 51.7684°N 3.7799°W, SN772092 |
Stone aqueduct built over a weir, carrying the Swansea Canal over the River Twrch. Its three massive arches make it the largest of the five aqueducts on the canal. Built in 1798 by Thomas Sheasby, it was innovative in using Hydraulic cement to line the trough instead of puddled clay. Its proximity to the Capitol Cinema gave it the local name of 'Capitol Bridge'. It was restored in 1995 but is not currently water-filled, the canal route on either side being dry. | Post-Medieval/ Modern (1798) |
GM396 |
| Crimea Colliery & Canal Quay | Coal mine | Ystalyfera | 51°45′01″N 3°48′07″W / 51.7504°N 3.8019°W, SN757072 |
The Crimea coalmine only operated for 8 years, from 1854 to 1862, and the site has been abandoned ever since. Amongst the regenerating woodland are the substantial ruins of a beam-engine pumping-house, a winding house and chimney, and a complete surface layout of a mid-19th-century colliery. A short tramroad led to a quay on the Swansea Canal, 200m south of the dry dock (GM397). | Post-Medieval/ Modern (1854) |

| Cilybebyll Auxiliary Unit Operational Base | Observation Post | Cilybebyll | 51°43′23″N 3°48′36″W / 51.723°N 3.8101°W, SN750042 |

Chain Home Low Radar Station, Margam | Radar station | Margam | 51°34′11″N 3°44′34″W / 51.5698°N 3.7428°W, SS793871 |
One of a network of early warning radar stations around the coast of Britain, constructed from 1941 to look for German bombers and shipping during World War II. They complemented the earlier Chain Home stations by being able to detect low-flying planes. The Margam station has three flat-topped buildings within the Country Park, high on the escarpment, overlooking Port Talbot and Swansea Bay. | Post-Medieval/ Modern (1940s) |
