Wikimedia UK and Wikimedia Community Ireland are delighted to to invite you to the Celtic Knot Online Celebration Day 2025, taking place virtually on Tuesday, 23rd September, from 1:00 pm to 4:00 pm (BST/IST).
This special online event invites contributors, advocates, and community members working with Celtic and other minority and minoritised languages for an afternoon of connection, collaboration, and celebration. Whether you’re a seasoned Wikimedian, a language activist, or simply curious about the power of open knowledge, this is your chance to be part of a growing movement.

What to expect
- Inspiring presentations and lightning talks highlighting new projects, breakthroughs, and stories from across Wikimedia’s language communities.
- Hands-on interactive workshops designed to spark fresh ideas and practical skills.
- Community-led activities that celebrate cultural diversity and language resilience.
- Opportunities to network, reconnect, and build collaborations with like-minded people across borders.

About the Celtic Conference

The Celtic Knot Wikimedia Languages Conference brings together people who are passionate about sharing knowledge in Celtic and other minority languages on Wikimedia platforms. The event provides an opportunity for contributors to connect, learn, and support each other in overcoming language barriers through collaboration, community building, and the use of technical tools.
Whether you’re working on Wikipedia, Wikidata, Wikisource, or related projects, the Celtic Knot provides a valuable opportunity to grow your skills and networks. The annual conference is a place where people working on growing and maintaining their communities (on Wikipedia, but also Wikisource or Wikidata) can meet, learn from each other, and support each other on topics like community growth, technical tools, or collaboration with partners.
Now in its eighth year, and supported by Wikimedia UK and local partners, the Celtic Knot continues to build on the momentum of past editions—including two successful online events.
