One year on, the 15,000 capacity state-of the-art rugby stadium is feeling like home for the region's supporters and sponsors and the Scarlets players and staff. The historic first game at the new facility was held on Saturday 15th November 2008 - fittingly Llanelli RFC v Cardiff RFC, a game which saw Llanelli triumph with a 32 - 3 win over their rivals.
And as a tribute to this landmark date, the Scarlets have invited troops from the Royal Welsh Guards recently returned from service in Afghanistan to mark the event.
The Scarlets players, staff and the region's many thousands of supporters will play tribute on Saturday to the brave men and women of Wales in the armed forces following this week's commemorations both on Remembrance Sunday and Armistice Day.
Captain Alex Rabbitt, Sniper Platoon Commander, who will lead the parade of honour at Parc y Scarlets said: "Having only recently returned from Iraq last Christmas, we the soldiers from C Company, Second Battalion The Royal Welsh, have now completed and returned from our first tour of duty in Afghanistan.
"It was a very hard six months and it is now really nice to be back home with our friends and families. A number of our troops are Scarlets supporters, so we are delighted to be part of the region's 1st anniversary celebrations.
"It is really good to be able to attend events such as the Scarlets match on Saturday as it reminds the public of the conflict in Afghanistan and the soldiers that are still serving there."
A group of 20 soldiers from C company, 2nd battalion Royal Welsh Guards will be walk out with the teams on Saturday and form a guard of honour in the middle of the pitch.
And to honour the Welsh guards, the Scarlets team will play in their Welsh 'green' away kit as a mark of respect for the soldiers. The away kit was chosen by the Scarlets to symbolise the region's Welshness and incorporates the colours of the Welsh flag with green being the prominent colour.
Paul Sergeant, Chief Executive of the Scarlets said: "I think I speak for most when we say that we have the utmost respect for these guys, who show remarkable character and commitment in what they do. We are delighted and honoured to welcome them to Parc y Scarlets and look forward to forging closer links with them in the future."
And celebrating Parc y Scarlets' first anniversary in style on the field will be Scarlets fly half Rhys Priestland who was the first to score at the ground with his boot - scoring 22 points during the Llanelli v Cardiff encounter. And rising star centre Jon Davies, who is currently with Wales, had the honour of the first try at the stadium and said: "It's always nice to get over in any game, but in such a special game... I will always remember that as a really proud moment."
To add to the ceremony and nostalgia, Scarlets Commercial Director, Rupert Moon will be going back down memory lane at the weekend as he recalls an important date in his playing career - Saturday 14th November 1992 when Llanelli recorded an historic 13 - 9 win over Australia at Stradey Park - another game which lives on in the history books.
The Scarlets will be showing the game on the big screen at Parc y Scarlets in the run up to the match v Worcester on Saturday afternoon.
Rupert Moon said: "It's going to be quite an afternoon on Saturday with plenty happening at the stadium including our full pre-match build-up in the indoor Supporters Village at Parc y Scarlets. It can be a bit quieter for the regions during the Wales autumn internationals, but after such a great performance by our young rising stars on Sunday against Harlequins, we are hoping our many Scarlets supporters will be there to support them at home and join us for a brilliant family afternoon out, particularly if some of the other club games are rained off due to the conditions. We hope to see everyone down here."
The Scarlets have another major anniversary to come before Christmas at their new home. Saturday 12th December marks the first anniversary of the region's first-ever European game at Parc y Scarlets - and it will be a big Parc y Scarlets occasion as the Scarlets welcome Leinster at home in the Heineken Cup.
