A virtual tour guide to help Dublin's 3.8 million visitors learn about its most famous landmarks was launched.
Information on tourist attractions across the city is available through a new smartphone application by pointing a mobile device at a building or landmark.
Frank Magee, chief executive of Dublin Tourism, said the capital will become the first city in the world to have its own app.
"It will inevitably be replicated by other leading tourist destinations around the world," he said.
The app covers the greater Dublin area and operates within a 10km radius from where the user is located.
Its contents will be sourced from the VisitDublin.com website's 7,000 pages of information and will initially cover 1,400 points of interest.
The Visit Dublin app allows visitors to move about Dublin and discover their interests.
Users can then access electronically-stored data about an attraction they are looking at, for example overlaid images, opening times or playing audio.
Other features include: Users can virtually move to destinations and virtually explore them before making a visit; 81 audio clips that allow users to find the closest point of interest; a special offers screen enabling bar, restaurant and tourism attraction owners to list discount coupons and a daily bulletin with news updates on new attractions, events and other tourist-related information.
The app can also function without any network connection, limiting roaming charges.
