The Aquincum Museum in Óbuda sits on the ancient Roman and Celtic ruins of the area, and this year, the museum is hosting a whole day of celebrations on 31 October. Halloween itself traces back to the Celtic Samhain, the last day in the Celtic calendar when it was believed that the boundary between this world and the world of the dead could open up and allow supernatural creatures to walk free. In honour of the holiday’s Celtic roots, the museum is offering a programme of events including pumpkin carving, face painting, fortune-telling, scavenger hunt, dancing and fire duels, and demonstrations of Celtic living practices.
