Heol-y-Cyw was founded in 1906 and has a fascinating history in Welsh rugby. For a long time, the base of operations was the Heol-y-Cyw Working Men's Club. However, the club went through a meteoric rise after the Second World War, and in 1978, a new clubhouse was built on the High Street. Such a milestone in the club's history was marked by "The King" Barry John opening the establishment in July of that year. Heol-y-Cyw provided a place for local players to play and socialise, and the clubhouse quickly became a social hub for the community, like many teams in the area.

The mark of a great side is making the most of what you have. Heol-y-Cyw quickly built a reputation for punching well above its weight. It resembles the village's outlook on life; as a small community of 540 people, Heol-y-Cyw often exceeds expectations. The people have an intense spirit where nothing is too big to overcome. Throughout its history, the club has managed to pull off some tremendous results for a relatively small team.

A prime example is the 1983 Brewers Cup, where the team stormed to Cardiff Arms Park in a giant-killing run. The Brewers Cup allowed less high-profile clubs like Heol-y-Cyw to take on the big dogs of Welsh rugby at the time. Baglan was victorious in the final, but getting that far was monumental. This was not Heol-y-Cyw's only success in cup competitions; in the Lyn Cup, they toppled the mighty Maesteg Harlequins to capture the gold. On a December night in the 1984 second round of the Schweppes Cup, Heol-y-Cyw travelled to the legendary Gnoll to take on the formidable Neath. Known as the 'Welsh All Blacks,' Neath was where many seasoned internationals played rugby. Even though the side went into the contest as underdogs, they were underrated and embodied the spirit of the town to give their opposition a real run for their money.

A monumental moment for any club is gaining WRU status; Heol-y-Cyw achieved this for the 1988/89 season and has been a fixture in grassroots rugby ever since. Fast forward to 2013, and Heol-y-Cyw took a trip to the Principality Stadium with their eyes firmly set on Rhydyfelin, bringing the Swalec Plate back to the village. They secured a 20-19 victory over their opposition, reinforcing their reputation for punching well above their weight.
