RTÉ Raidió na Gaeltachta is celebrating 40 years on air today, Monday April 2.

The national Irish-language station came on air for the first time at 3pm on Easter Sunday 1972, becoming the second legal radio station in the State.

The service began with seven broadcasters and initially broadcast for just over two hours a day to Gaeltacht areas.

At 3pm today, Monday April 2, Seán Bán Breathnach was joined in studio by five of those original seven broadcasters – Breandán Feiritéar, Seán Ó Tuairisg, Maidhc P Ó Conaola, Máirtín Ó Fátharta and Timlín Ó Cearnaigh – for a special celebratory programme.

As part of the 40th anniversary celebrations, on Easter Sunday, April 8, the station will have live programming and music from An Cheathrú Rua – the place from where Ó Riada's Mass was broadcast on the first day of broadcasting in 1972.

There will also be several live concerts over the coming months, and President Michael D Higgins will visit the station HQ in Casla in Connemara in May.
