Shane Williams celebrates Wales' second Test win in 2004

The tourists have never played a Test in the region, despite the number of Welsh language speakers who live there.

Puerto Madryn, founded in 1865 by Welsh settlers, will host the match.

Wales team manager Alan Phillips said: "We are delighted to be playing for the first time in Patagonia. It will be an unique opportunity for the Welsh team to play in the Welsh colony."

Wales will then move on to Buenos Aires for the second Test on 17 June.

A group of 153 Welsh settlers arrived in the Chubut province via the tea clipper SS Mimosa from Liverpool on 27 July, 1865, with the aim of setting up a Welsh-speaking colony away from the influence of England.

They were granted 100 square miles of land along the Chubut River by the Argentine government.

Puerto Madryn was originally founded under the name Porth Madryn in honour of the founding father of the Welsh immigrants - Sir Love Jones-Parry, the Baron of Madryn.

Thousands of Welsh people left their homeland in search of a brighter future in South America in the 19th century.

The trip will be the fourth the Wales national rugby team have made to Argentina, but some Welshmen have previously played rugby in Patagonia.

Jonathan Davies, Ieuan Evans and Carwyn Davies played for a Patagonian team in the Argentine National Sevens tournament in the late 1980s.

Alejandro Risler, president of Argentina Rugby Union (UAR), said: "It's a policy to take the Pumas to different places in our country.

"We've played Tests in other provinces, such as Salta, Cordoba and Tucuman, and now it is time to go to Chubut.

"After looking at the stadium, pitch and hotel facilities the UAR accepted the proposal of the Chubut union to stage the game.

"This means that for the first time in our history we will be playing in Patagonia."

The Test match was originally scheduled for the Saturday but has been put back 24 hours to avoid a clash with Argentina's football team, which is playing a World Cup match against Ivory Coast on 10 June.
