Boston Kuk Sool Won have presented Great Ormond Street Hospital with a cheque for £670.
The club raised the money through various ventures, which culminated in a two-hour demonstration.
There, members showcased their skills – from block breaking to weapons work – in front of invited guests and dignitaries.
Kuk Sool members wanted to donate to the children’s hospital, due to their ethos of ‘giving something back’.
Other cash was raised via raffles, quizzes, sponsored events and a pumpkin competition.
Classes are held every Monday and Thursday at Boston High School.
Children and beginner classes run from 6-6.45pm, with adult sessions being held between 7.30-8.45pm.
Anyone interested in the club should contact principal instructor Sonny Boyall on 07710 444662.
