The organizers of the bonfire of San Juan del barrio Tirol-Camilleri want to remind us that his fire is located in front of the Kabuki and stick it on fire June 24 at 00:00.
As can be read in wikipedia, the Night of San Juan is a festival of pagan origin, not very old often linked to light fires or fires, linked with celebrations in which they celebrated the arrival of the summer solstice in the hemisphere North, whose principal rite is a fire.
The purpose of this ritual was "giving more power to the sun", that from those days, was becoming "weaker"-the days are getting shorter until the winter solstice.
Symbolically fire also has a function "cleansing" in people watching him.
It is celebrated in many parts of Europe, but is particularly strong in Spain, Portugal (Fogueiras de São João), Norway (Jonsok), Denmark (Sankthans), Sweden (Midsummer), Finland (Juhannus), Estonia (Jaanipäev) and the UK (Midsummer).
