Experience Derry’s Epic Halloween Carnival in 2026

Come and Enjoy Europe’s Largest and Spookiest Halloween Celebration in Derry, Northern Ireland

The spiritual home and birthplace of Halloween is Ireland. The holiday evolved from Samhain, an ancient Celtic harvest festival celebrated across the island for over 2,000 years.

Specific ancient locations deeply tied to the holiday’s roots include:

  • The Hill of Ward (Tlachtga), County Meath: Widely considered the ancient epicenter of Samhain. The Celts lit massive ceremonial bonfires here.
  • Oweynagat (Cave of the Cats), County Roscommon: Located near the Rathcroghan archaeological complex. Ancient legends called this cave Ireland’s “Gate to Hell,” where monsters emerged.
  • Derry City, County Londonderry: Derry hosts Europe’s largest Halloween festival, transforming the historic walled city into a massive carnival of the dead to honour its Celtic roots.
