Senghenydd (Welsh: Senghennydd) is a village in the Aber valley, roughly four miles north-west of the town of Caerphilly. Traditionally within the county of Glamorgan it is in the community of Aber Valley in the county borough of Caerphilly, Wales. The population of the Aber Valley in the United Kingdom Census 2001 was 6,696.^[1]

Origin of the name

The name derives originally from the name Sangan + suffix ydd, probably meaning "the land or territory associated with Sangan". The suffix 'ydd' is often used in Welsh, following a personal name, to denote ownership, as in 'Meirionnydd' or 'Eifionydd'.

Historically the name has appeared in a number of different forms, including: 'Seinhenit' (c.1179), 'Seighenith' (c1.194), 'Seynghenyth' (1271), 'Senghenyth' (1314), 'Seynthenneth' (1476), 'Seignhenith Suptus et Supra Cayach' (1578–84).

Alternatively, the name may be a spelling variant, from 1326, of 'Seint Genith', from Saint Cenydd. The local church and school have taken this name, as has the nearby 20th-century settlement of Trecenydd.^[2]

History

Senghenydd was originally a rural farming community, which became industrialised with the discovery of coal in the late 19th century. With the closure of the coal pits in the second half of the twentieth century, most people in the town now commute outside the Aber Valley for employment.

Early history

Tradition states that there was a monastery built in the area surrounding the town built by St Cennydd; whilst this is disputed, the area Senghennydd was named after him. The son of Cennydd, St Ffili is said to built a fort in the area, making the name of Caerphilly (Ffili's Fort in the Welsh language).

The town was also a stronghold for the Welsh during the late 11th century. By the 13th century, it remained under Welsh hands and the Welsh chieftain Ifor Bach (hence the name of the local Welsh school in the town). Ifor Bach's great grandson Llewelyn Bren (Llewelyn ap Gruffudd ap Rhys) was the last Welsh lord of Senghenydd but lost control of his lands after the 6 week siege of Caerphilly Castle and a brief battle at Castell Morgraig a welsh built castle at Cefn-Onn ridge which was possibly built by the Lords of Senghenydd.

It is also reputed that Ifor Bach built a medieval castle on the site that is now occupied by Castell Coch.

Llewelyn Bren was later sent as a prisoner first to Brecon and then to the Tower of London along with his family

In 1318 Llywelyn became the prisoner of the ruthless Hugh the younger Despenser, one of King Edward's favourites at court who had become Lord of Glamorgan in November 1317 and thus the largest land owner in South Wales, and was a great rival of Mortimer. Without the king's direction, he took Llywelyn Bren to Cardiff Castle where he had him hanged, drawn and quartered without a proper trial. After the parts of his body were exhibited in various parts of the county he was buried in the Grey Friars at Cardiff. Llywelyn's lands were seized by Despenser. This action was condemned at the time and later used as example of the Despensers' growing tyranny. Despenser also imprisoned Lleucu and some of her sons in Cardiff.

In October 1326 following the successful rebellion led by Roger Mortimer the Despensers and Edward had further cause to regret their actions in Glamorgan after they were forced to flee there. Edward and the Despensers' attempts to raise troops locally were (understandably) a dismal failure. This led to their capture in November; then Hugh endured the same death he inflicted on Llewelyn when he too was hanged, drawn and quartered.

With the overthrow of Edward II, the estates in Senghenydd were restored (11 Feb. 1327) to Llywelyn Bren's sons—Gruffydd, John, Meurig, Roger, William and Llywelyn. The Earls of Hereford continued to pay at Brecon an allowance to their mother Lleucu until 12 April 1349.

Coal mining

Senghenydd, along with its neighbouring town Abertridwr, make up the majority of the Aber Valley, and became urbanised in the 1890s, when the Universal (1891) and Windsor collieries were sunk in this region of the South Wales Coalfield.^[3]

The Universal Colliery at Senghenydd suffered the first of two major gas and coal dust explosions on 24 May 1901. Damage was sustained to both shafts, resulting in a restricted rescue attempt, and 81 of the 82 men working in the mine were killed.^[4]

Miners' Rows, Senghenydd

On the 14 October 1913, Senghenydd suffered the worst mining disaster in Britain's history, when a second gas explosion occurred at the Universal Colliery, resulting in the loss of 439 lives, plus one rescuer. Many of the surviving miners went back to help their workmates who were either trapped or buried alive.^[5]

Universal Colliery was finally closed on Friday 30 March 1928 (except for a ventilation shaft) with the loss of 2500 jobs.^[6]

Health research

Men from Senghenydd participate in one of the world's longest running epidemiology studies – The Caerphilly Heart Disease Study. Since 1979, a representative sample of adult males born between 1918 and 1938, living in Caerphilly and the surrounding villages of Abertridwr, Bedwas, Machen, Senghenydd and Trethomas, have participated in the study. A wide range of health and lifestyle data have been collected throughout the study and have been the basis of over 400 publications in the medical press. A notable report was on the reductions in vascular disease, diabetes, cognitive impairment and dementia attributable to a healthy lifestyle.^[7]

Transport

Senghenydd is served by the B4263 road to Caerphilly, and connects to Nelson via roads over Mynydd Eglwysilan to the north.

Sport

Senghenydd Rugby Football Club is a rugby union club affiliated to the Welsh Rugby Union who have played in the town since 1898.
