The football club are, according the cover of their programme "South Wales Oldest Football Club". The club were formed in 1889 and were founder members of the South Wales League. The club became the league's first champions. In 1906 after dominating the South Wales League Treharris became one of the first clubs to play over the border when they joined the Western League. Four years were spent in the Western League and in their final campaign they became champions, and along with Cardiff City were elected to the Southern League. Just four seasons were spent in the second division of the Southern League before they resigned / were not re-elected in 1914. I stand to be corrected but I believe the club has been ever present in the Welsh League ever since. In 2008 they merged with local Merthyr League club Treharris Western to give us their present title. This season both Treharris and Llangeinor sit in mid-table with only three places and four points between them at the start of play. The two sides played each other three days ago @ Llanegeinor with Treharris recording a 2-0 victory.
The ground is certainly one of the most interesting ones I have ever come across and one that I felt oozes character and charm in a rustic kind of way. We were not charged any admission or any money for the programme, though anyone who turned up nearer to kick-off was charged an admission though how much I don't know. The game was fairly even and played in the right spirit, with the visitors I would say shading affairs overall. Despite being an end of season game both sides had plenty of chances, though the majority did not trouble either keeper. Llangeinor took the lead on twelve minutes when following a double save from the Treharris keeper Jordan Mortimer headed the ball home from five yards out. Both sides continued to create chances but the not further scoring occured. The second half continued in the same vain as the first but following a spell of possession and territory for around ten minutes Llangeinor hit Treharris on the counter attack with Josh Ellis cooly slotting the ball into an empty net following a good save from the home keeper who injured himself in the process. The home side never gave up and got, what turned out to be a consolation goal in stoppage time when Ross Porter hit an unstoppable shot into the top right hand corner from fully thrity five yards.
