The Coinage Act 1816 (56 Geo. 3. c. 68), also known as the Coin Act 1816 or Liverpool's Act, defined the value of the pound sterling relative to gold. One troy pound of standard (22-carat) gold was defined as equivalent to £46 14s 6d., i.e. 44½ guineas, the guinea having been fixed in December 1717 at £1 1s exactly. According to its preamble, the purposes of the Act were to: prohibit the use of silver coins (which would now be of reduced weight, 66 shillings rather than 62 shillings per troy pound), for transactions larger than 40s establish a single gold standard for transactions of all sizes.

South Wales Fire and Rescue Service (SWFRS; Welsh: Gwasanaeth Tân ac Achub De Cymru) is the fire and rescue service covering the ten Welsh principal areas of Blaenau Gwent, Bridgend, Caerphilly, Cardiff, Merthyr Tydfil, Monmouthshire, Newport, Rhondda Cynon Taf, Torfaen and Vale of Glamorgan. SWFRS was created in 1996 by the Local Government (Wales) Act 1994, which reformed Welsh local government. It was created by a merger of the previous fire brigades of Mid Glamorgan, South Glamorgan and Gwent. It covers an area of around 1,100 square miles (2,800 km2) with a population of around 1.5 million.The fire authority which runs the service is a joint-board made up of councillors from the ten local authorities covered by the service.Since October 2017, SWFRS has shared its control room with Mid and West Wales Fire and Rescue Service and South Wales Police at the police headquarters in Bridgend, an arrangement that is expected to save £1 million annually across both fire and rescue services.

The tower, which is about 70 feet (21 m) high, contains a peal of six bells. The living is a vicarage. Llantrisant Church is a Grade II* listed building.

On 12 August 1893 a T-link broke beneath a locomotive running down the bank from Merthyr to Cardiff hauling a passenger train. This allowed an underhung spring to break away from the engine and foul the wheels of the leading van, derailing the entire train. The first six carriages ran down an embankment, killing thirteen.

Penychen was a possible minor kingdom of early medieval Wales and later a cantref of the Kingdom of Morgannwg. Penychen was one of three cantrefi that made up the kingdom of Glywysing, lying between the rivers Taff and Thaw, the other two being Gwynllwg and Gorfynydd. According to tradition, these cantrefi were created on the death of Glywys (c.480 AD), the first king of Glywysing, when the kingdom was divided between his three sons: Pawl, Gwynllyw and Mechwyn. But our knowledge of the early history of the kingdom is very uncertain, being mainly sourced from medieval documents and traditional pedigrees. Pawl was the ruler of Penychen and on his death (c.540 AD) passed the cantref on to his nephew.Pawl's brother Gwynllyw was the ruler of Gwynllwg and upon his death it is said that the cantref passed to his son Cadoc (Cadwg), also known as St. Cadoc. Cadoc would later take control of Penychen, but when he was killed by the Saxons he had no heirs, and both cantrefi fell under the control of Meureg of Gwent and were absorbed into his kingdom. After the Norman conquest of South Wales, the southern parts of Penychen, on the Bristol Channel, came under the direct rule of the Norman Marcher Lords and their descendants, but the rest (the commotes of Rhondda Valley and Miskin) remained under the rule of local Welsh lords, who paid homage to the powerful Norman lords but still retained a degree of independence, which they were very ready to defend. In the Middle Ages Penychen contained two important ecclesiastical centres: the episcopal seat of Llandaf, and Llancarfan, a clas connected to the early author Caradoc of Llancarfan.
