Culture Night has been taking place tonight with events in towns and villages around the country, as well as online.
Due to Covid-19 restrictions, there are not the same large-scale gatherings as before. However, organisers said the programme would recognise the importance of the creative sector.
Artists and arts organisations have been hard at work around the country, ensuring that there would be free access to events in the community and online.
More than 800 events were planned, with all details on the Culture Night website.
RTÉ also marked the occasion with a range of special broadcasts across television, radio and online, including a Culture Night Nationwide special, a performance from the RTÉ National Symphony orchestra live on RTÉ Lyric FM and RTÉ Culture, as well as a special edition of the radio arts show Arena.
Culture Night organisers said they are committed to the health and safety of participants, and that they hoped this year's programme would provide an opportunity to recognise the importance and value of the creative sector during this very difficult year.
