Gravity Fields Festival 2014 was hailed an outstanding success by organisers South Kesteven District Council.
The audience topped 60,000 for outdoor events, shows and exhibitions over the five days - 15,000 for Saturday's transformation of the town alone.
Ticket sales over 120+ events were well up compared to the number sold in 2012, some 38 schools attended events in the education programme and new venues such as St Wulfram's Church added a whole new dimension.
Tickets were sold to customers in London, Canterbury and Devon and visitors from America and Australia illustrated the festival's widening international appeal - including two Japanese diners at the closing supper.
Town food retailers reported Saturday trade better than Christmas, bars were packed and the George Centre, host to a four day science fair, reported footfall had more than doubled compared with the same day last year.
