​Welsh-speaking children from Ysgol yr Hendre, Trelew, in Patagonia, have been welcomed to the Senedd by Presiding Officer, Dame Rosemary Butler AM.
The pupils, aged between 10 and 11, have travelled to Wales to take part in the Urdd Eisteddfod near Caerphilly.

The visit also coincides with celebrations to mark the 150th anniversary of the departure of Welsh people to Patagonia, from Liverpool, on board the Mimosa in 1865.
"It is great to welcome these Welsh speaking young people from the other side of the world to the seat of Welsh governance," said Dame Rosemary.
"Those Welsh people who left Liverpool 1865 were setting sail for a better life and for a life where they could live through the Welsh language.
"It is a privilege for me to welcome their ancestors back to Wales 150 years later and to know that they have succeeded in creating a Welsh community on the other side of the world where the language is still at its heart."
Ysgol yr Hendre, in the Chubut area of Patagonia, was established in March 2006 following the success of Ysgol Feithrin y Ddraig, the Welsh-language nursery which was established in 1996.
It is the first Welsh/Spanish bilingual school in Patagonia.
During their visit to the Senedd they sang a song for the Presiding Officer which celebrated the differences and similarities between Wales and Y Wladfa in Patagonia.
Ysgol yr Hendre teacher, Catrin Morris, said "The visit to Wales is a dream come true for every pupil, they were all very eager to come.
"The parents have worked very hard to raise money for the visit to ensure their children had the chance to improve their Welsh and to build a solid foundation for their education."
