Hundreds attended celebrations in Guildhall Square on Sunday to mark the second anniversary of the Líofa campaign to increase fluency in Irish.
The celebrations were hosted by Culture Minister Carál Ní Chuilín and involved musicians and children’s entertainers.
Local traditional musicians entertained the crowds from a specially-erected stage in Guildhall Square while stalls were erected selling Irish language books.
Material designed to help learners master the language was also provided.
The Líofa campaign was launched two years ago to increase the number of fluent Irish speakers in the North by 2015. The department provides online help to learners of all levels and issues regular newsletters designed to encourage people to speak Irish.
Minister Ní Chuilín had initially set a target of 1,000 people but to date more than 4,000 people have signed up.
Despite the rain, the hundreds of people who attended the celebrations enjoyed the music and dancing and the entertainment provided.
