National Treasures is a crowdsourced archive project that collects everyday objects and cultural stories to highlight Ireland's heritage over the past century. The RTÉ television series invites the public to submit objects representing significant moments and experiences, creating a digital archive that reflects Ireland’s diverse narratives.

The project emphasises how personal memories and artefacts contribute to national history, showcasing how even simple items can reveal social changes and cultural values. By involving ordinary citizens, National Treasures honours individual stories and connects viewers to shared Irish experiences.

The campaign includes a website, roadshow events, a four-part TV series, and an exhibition at the National Museum of Ireland, fostering broad participation and community engagement. This initiative highlights the importance of personal memory in shaping collective history and strengthens the understanding of Irish identity for future generations.
