Eisteddfod 2025: What is this Welsh festival all about?
The Urdd Eisteddfod is the largest cultural festival in Europe where thousands of young people from all over Wales join together to celebrate the Welsh language.
As well as stalls and activities, there are also lots of competitions taking place in music, literature and performing arts for young people of all ages - all in the Welsh language.
This year it's being held at Margam Park, Port Talbot.
De-Graft went along to see what it was all about and heard from some of the young people taking part.
