Along with St. Paddy's day Halloween is one of the two festivals that we Irish (along with fellow Celtic races) can claim ownership of. It really is a very ancient Celtic festival marking the end of Summer and the night when the dead come back to visit. It long pre-dates Christianity and is still celebrated as vigorously here today as it was thousands of years ago. Indeed the early Christians realising that they couldn't stamp out the old pagan festival tried to sanitise it by making the following day "All Saints Day". Of course the nature of the celebration has changed a bit and having exported the festival to the USA we have re-imported some of the commercial American approach. Nevertheless it is a great night particularly for kids. Fireworks and bonfires light up the sky. Children dress up in costumes and visit their neighbour's collecting sweets and treats (the appellation "trick or treating" is an American import but the practice originated here).
