The city is the birthplace of the modern hot air balloon, dating back to 1967 when the Bristol Belle was built and flown in the area. Over the years, many weird and wonderfully shaped balloons have graced the skies - some of which have made regular appearances at balloon festivals in the UK and around the world. With the 48th edition of the Bristol International Balloon Fiesta returning from 7-9 August, here is a roundup of some of the most wacky shapes.

Created by Bristol's Cameron Balloons simply "for fun", the 150ft (46m) giant has become a familiar face at festivals from Bristol to Switzerland's Chateau d'Oex. Slick the Dragon Image caption, Crowd-favourite Slick the Dragon frequently appears at mass ascents at events in the UK No mass ascent feels quite complete without Slick the Dragon. The giant green character, complete with distinctive blue shirt, has become one of the most-loved regulars on the UK ballooning circuit, delighting crowds wherever he lands. Oggy the Friendly Dragon Image caption, Oggy the Friendly Giant is more than twice the size of a normal hot air balloon Oggy the Friendly Dragon is one of the UK's largest special-shape hot air balloons, towering at around 143ft (43.6m) tall. His big smile and bright colours make him a fan-favourite at Bristol's annual fiesta. Action Man Image source, MJ Ballooning Image caption, The Action Man balloon is one of the most complex designs Frozen forever in mid-skydive, Action Man looks as though he has leapt from an aircraft rather than risen gently from a field. Built by Cameron Balloons in 1997 and later restored by MJ Ballooning, the Action Man balloon is one of the most complex special shapes around. Due to his ageing fabric, he now usually appears tethered rather than taking to the skies.
