Culture Vannin, the local organisation for all things Manx, has this interesting information on the old tradition of Hop Tu Naa - the celebration of the traditional Celtic festival of Samhain, the start of winter (Oie Houney).
"Hop-tu-naa is the oldest continuously-existing tradition in the Isle of Man. Celebrated on the 31st of October, Hop-tu-naa is the Manx equivalent of Halloween, with some very important differences. Unmistakably, one of the key features of hop-tu-naa is the "moot" (turnip), which is hollowed out and decorated; there is also a range of popular folk songs with regional differences, in both English and Manx; there is a traditional folk dance still practiced across the Island today; and there are some unusual customs and supertitions which link back to the ancient Celtic beliefs about this time of year."
Many public Hop-tu-Naa events take place across the Isle of Man each year, most of which today include competitions for artistically carving turnips and the singing of traditional songs.
