Since 2006, the Athenry Heritage Centre in partnership with Galway County Council have curated Athenry's Walled Towns Day.

This one day festival provides a programme of events which showcases the Anglo-Norman influences in the medieval town of Athenry.  The event is held in the Community Park, Athenry Castle, the Heritage Centre and the Community Hall.

Athenry Walled Towns Day is designed to be inclusive, accessible, fun and free for all to attend. The programme reflects the medieval history of Athenry and the event is a platform for local craft and artisan food producers to showcase their products.  

The displays range from falconry, arts & crafts, have a go archery, battle reenactments, displays of weaponry, children's craft workshops, medieval music, storytelling and puppet shows.

Athenry Castle is used for various lectures, children's craft workshops and music displays in the Great Hall. The event is usually held at the beginning of Heritage Week which is the last week of August and attracts up to 5000 people on the day.  The event is one of many Walled Towns Days held throughout Ireland and is supported by the Heritage Council and Galway County Council.
