The Bridgwater Guy Fawkes Carnival in Somerset, which attracts over a 150,000 people to the town each year, will be taking place on Saturday 4 November.
The celebration dates back to the Gunpowder Plot of 1605 and its purpose is to raise money for local charities.
Bridgwater marks the start of the Somerset County Guy Fawkes Carnivals - this is the biggest circuit that most of the clubs work up to.
The Wessex Circuit (including Shafestbury, Gillingham, Wincanton etc.) and the South Somerset circuit (including Taunton, Wellington, Chard, Ilminster etc.) have now finished.
Organisers say a lot of work is done to to put the carnival together from the engineering and woodwork, to the painting.
The clubs involved not only include those based in Somerset, but also from Devon and Dorset. As well as the big, illuminated carts, there are also walking and individual entries.
There are different types of carts, including feature carts, where there are lots of moving parts and people dancing, and 'Tableau' carts, which is a static show with people frozen in positions.
Each carnival will pick winners and overall prizes will be handed out in a big awards evening after the Guy Fawkes circuit has finished.
The carnival brings a lot of competition. Last month, at Bridgwater Town Hall, the Renegades won the annual carnival warm-up for the first time and are now hoping to take that success to the procession.
Spectators say the cart-building site is almost like a little village - all to be revealed this weekend.
