Brighton Fringe Festival is the largest art festival in England, and it takes place every year in May. It is about 4 weeks long every year filled with lots of events and exhibitions. Everybody can submit to participate, the registration is open now until the 31st of January. Brighton Fringe Festival is also a registered charity.
Next year, in 2014 the date of the Festival is: 3 May – 1 June. I think it is really worth to visit the festival and the city of Brighton or even participate if you are an artist. You can also apply to be part of the festival as a volunteer.
