The seven-mile boundary walk of the ancient borough of Llantrisant dates back 660 years and attracts more than 10,000 people to the town.
Organised by Llantrisant Town Trust with the support of Llantrisant Community Council it is only held every seven years and has become recognised as one of the oldest community traditions in Wales.
It began in 1346 following the presentment of a charter by the Lord of Glamorgan to create freemen of Llantrisant.
There will be plenty of family fun in store throughout the streets including concerts, banquets, entertainers, radio roadshows, a fairground, stalls and activities.
Dean Powell, Clerk to Llantrisant Town Trust said: “Beating the Bounds is an eagerly awaited festival and ceremony in the historic town of Llantrisant and attracts many thousands of visitors to the locality.
“It comes as a major boost to the local economy as residents and businesspeople alike eagerly await the opportunity to showcase their town to a wider audience.
“In 2017 we plan to provide one of the biggest Beating the Bounds to date which will include a whole host of events and activities over a five-day period.
“This has always been a successful event for the entire community and with their continued support we look forward to June 2017 with great expectation.”
Starting on Wednesday June 14 Beating the Bounds will be launched with a celebrity concert at Llantrisant Parish Church featuring the world-famous Treorchy Male Choir and Llantrisant Primary School.
There will be a social evening for the Freemen of Llantrisant and the launch of a new history guide book of the town on Thursday June 15.
On Friday June 16 internationally renowned big band singer Jeff Hooper will entertain the Beating the Bounds Banquet in the Castle Green Marquee.
The Beating the Bounds ceremony takes place on June 17 while a host of performers ranging from local groups and brass bands to choirs and folk dancers entertain the crowds throughout the streets. There will also be a fairground attraction and activities area provided by the army and emergency services.
Following a service at Llantrisant Parish Church at 12noon the seven mile walk will begin with a procession throughout the old town led by the celebrated Cwm Tawe Youth Band.
Llantrisant Town Trust will follow with their historic town mace, dated 1633 and older than the one used in the House of Commons. On reaching nearby Cross Inn the trustees will literally “bounce” children on one of the ancient boundary stones – a tradition dating back to the 14th century.
The fully-marshalled boundary walk includes Brynteg, Llantrisant Common to the Royal Mint and Llantrisant Golf Club before crossing through Talbot Green to Cross Inn and back to the hilltop town.
Beating the Bounds will conclude on Sunday June 18 with a guided history walk before a spectacular Comedy Night at the Castle Green Marquee hosted by Paul Sinha, the comedian, broadcaster and quiz player of “The Chase”.
Funding for Beating the Bounds has been provided by Llantrisant Community Council with the support of Llantrisant Town Trust and a number of donors including Abbey Glass, Blakemore, Balmoral Tanks, Pontyclun Community Shop, Devonalds Solicitors, Persimmon Homes and by public subscription along with fundraising activities at The Bear Inn.
Support is also being provided by Rhondda Cynon Taf Council and South Wales Police.

The tradition of Beating the Bounds began in 1346 when residents of the town were presented with a Charter allowing them to become a self-governing Corporation town. This also gave them grazing and other trading rights along with the management of extensive lands and property.
Shortly afterwards many of those early “Freemen” fought as longbowmen for the Black Prince at the Battle of Crecy in northern France, beating the French and claiming the three ostrich feathers which have been worn by every successive Prince of Wales since.
The Charter of 1346 conferred many privileges on the Burgesses –or Freemen - of Llantrisant and these were exercised within and bounded by the “liberties of the borough” – in other words, the boundary.
Beating the Bounds stemmed from the rights of the original Charter which allowed the Freemen to impose their power and rights on the designated ancient boundary of the town.
Within the boundary of the ancient borough of Llantrisant they could enforce their commercial and trading rights and other privileges granted by the Charter of 1346.
By walking the boundary they were ensuring that those rights and privileges had not been infringed upon.
