The trophy will be re-presented to the team by the first minister at the Senedd
Roger Pride, Managing Director of Cardiff & Co, talks to Business Correspondent Carole Green about the effect this weekend's match has had on Cardiff.
"A typical Six Nations game will bring in about £10 million to the city. This will have brought in considerably more" he said.
"This could be regarded as the first social media Grand Slam. The people who've come to city and had a great time are going to be tweeting and on facebook. These images are going to be sent all around the world".
The Six Nations crowds gave some Cardiff business owners a lot to celebrate too.
John Williams, manager of Cardiff's Shop Rugby says weekend sales were "beyond all expectation".

Wales captain Sam Warburton reflects on how the work the team have put in off the pitch, at their training camps in Poland, and in the way they conduct themselves, has paid off with their Six Nations triumph.
Ian Evans has tried to play down his individual role in Wales' Grand Slam triumph. The Ospreys lock is the only man to have played every minute of every game in this year's tournament, having returned from the international wilderness. But, he said, "it is more about the team effort than myself."
Wales captain Sam Warburton says the team is looking forward to saying 'thank you' to the fans, at a special event in Cardiff Bay organised for Monday evening. The Welsh Government has invited the squad and backroom staff to the Senedd to congratulate them on their Grand Slam triumph.
We know it is a great honour for us to be invited to the Senedd and if fans turn up to greet us it will make for a great occasion. All of us know how important rugby is here in Wales and we are humbled by the level of support we get from followers of our sport and from the general public.
Fans have been asked to arrive for 6pm on Monday. The First Minister Carwyn Jones will then present the Six Nations trophy to the captain and coach Warren Gatland.
