The most common aspect of modern May Day celebrations is the preparation of a flower wreath from wild flowers, although as a result of urbanisation there is an increasing trend to buy wreaths from flower shops. The flowers are placed on the wreath against a background of green leaves and the wreath is hung either on the entrance to the family house/apartment or on a balcony. It remains there until midsummer night. On that night, the flower wreaths are set alight in bonfires known as St John's fires. Youths leap over the flames consuming the flower wreaths. This custom has also practically disappeared, like the theatrical revival of Adonis/Dionysus/Maios, as a result of rising urban traffic and with no alternative public grounds in most Greek city neighbourhoods.
