Llanvabon

Nelson (Welsh: Ffos y Gerddinen) is a village and community in the County Borough of Caerphilly, Wales. It sits five miles north of Caerphilly and ten miles north of Cardiff, at the lower end of the Taff Bargoed Valley, and lies adjacent to Treharris, Trelewis and Quakers Yard.

Nelson Glam railway station served the village of Nelson, in the historical county of Glamorganshire, Wales, from 1900 to 1932 on the Llancaiach Branch.

Llancaiach railway station was originally opened by the Newport, Abergavenny and Hereford Railway on the Taff Vale Extension which later amalgamated with the Great Western Railway between Pontypool and Quakers Yard. The station served the village of Nelson and the hamlet of Llancaiach in the county borough of Caerphilly from 1858 to 1912, when a more modern station was built.

Mynydd Eglwysilan is a 355-metre-high hill in the Caerphilly county borough in South Wales 3 km to the south of Nelson and a similar distance southwest of Ystrad Mynach. To its south is Senghenydd at the head of the Aber Valley. Like neighbouring Cefn Eglwysilan, the hill is named after the hamlet of Eglwysilan 4 km to the southwest, the church here being dedicated to an obscure Saint Ilan. Remains of a linear earthwork known as Senghenydd Dyke stretch across the southern side of the hill. It is considered to mark the edge of an extensive 13th-century deer park associated with nearby Caerphilly Castle.

Llancaiach is a hamlet just north of the village of Nelson, Caerphilly, Wales.

Nelson and Llancaiach railway station served the village of Nelson and the hamlet of Llancaiach in the historic county of Caerphilly, Wales, from 1912 to 1964 on the Rhymney Railway.

Llancaiach Colliery was a coal mine in the South Wales Valleys, located just to the north of the village of Nelson and just to the south of Llancaiach Fawr Manor. It was opened by Thomas Powell in 1811, and from 1841 was served by the bespoke Llancaiach Branch line of the Taff Vale Railway.The mine closed in 1887.

Llancaiach Fawr Manor is a Tudor manor house near the village of Nelson, located just to the north of the site of the former Llancaiach Colliery in the heart of the Rhymney Valley in South Wales. The semi-fortified house was built on the site of an earlier medieval structure, either on top of the previous dwelling or possibly incorporated within the eastern end of that building. It is a Grade I listed building and is now best known as the home of Colonel Edward Prichard (died 1655), who hosted a visit by King Charles I of England in 1645. Llancaiach Fawr Manor was at one time thought to have predated the Acts of Union between Wales and England of 1536 and was talked about in John Leland’s Itinerary of 1537. The manor house is thought to have been built in about 1530 for one Dafydd ap Richard. (Prichard being a modernised form of the patronymic "ap Rhisiart"). However, dendrochronology results (from a Time Team excavation) indicate a felling date for the roof timbers of 1548–1565, later than was originally thought.The Manor is considered to be one of the most important gentry houses to have survived from the 16th and 17th century period. It is now open to visitors as a living history museum.

Universal Colliery was a coal mine located in Senghenydd in the Aber Valley, roughly four miles north-west of the town of Caerphilly. It was in the county borough of Caerphilly, traditionally in the county of Glamorgan, Wales. Started in 1891, it became a ventilation facility for the Windsor Colliery in 1928 before complete closure in 1988.

The Senghenydd colliery disaster, also known as the Senghenydd explosion (Welsh: Tanchwa Senghennydd), occurred at the Universal Colliery in Senghenydd, near Caerphilly, Glamorgan, Wales, on 14 October 1913. The explosion, which killed 439 miners and a rescuer, is the worst mining accident in the United Kingdom. Universal Colliery, on the South Wales Coalfield, extracted steam coal, which was much in demand. Some of the region's coal seams contained high quantities of firedamp, a highly explosive gas consisting of methane and hydrogen. In an earlier disaster in May 1901, three underground explosions at the colliery killed 81 miners. The inquest established that the colliery had high levels of airborne coal dust, which would have exacerbated the explosion and carried it further into the mine workings. The cause of the 1913 explosion is unknown, but the subsequent inquiry thought the most likely cause was a spark from underground signalling equipment that could have ignited any firedamp present. The miners in the east side of the workings were evacuated, but the men in the western section bore the brunt of the explosion, fire and afterdamp—a poisonous mixture of carbon dioxide, carbon monoxide and nitrogen left after an explosion. Fires in the workings hampered rescue efforts, and it took several days before they were under control. It took several weeks for most of the bodies to be recovered. The subsequent enquiry pointed to errors made by the company and its management leading to charges of negligence against Edward Shaw, the colliery manager, and the owners. Shaw was fined £24 while the company was fined £10; newspapers calculated the cost of each miner lost was just 1 shilling 1+1⁄4d (about equivalent to £6 in 2021). In 1981 a memorial to the men who died in the disaster was unveiled by the National Coal Board, followed by a second in 2006, to honour the dead of both the 1901 and 1913 explosions. In October 2013, on the centenary of the tragedy, a Welsh national memorial to those killed in all Wales's mining disasters was unveiled at the former pithead, depicting a rescue worker coming to the aid of one of the survivors of the explosion.

Senghenydd railway station served the town of Senghenydd, in the historic county of Glamorgan, Wales, from 1894 to 1964 on the Senghenydd branch of the Rhymney Railway.
