The team of 49 athletes were among the 2,000 competitors with intellectual (learning) disabilities from 58 countries who took part.
GB won medals in each of the seven sports they competed in, with cyclist Leanne Peters claiming three golds.
The 29-year-old from Blanefield, who represents Scotland West, won the 5k and 10k road races and 10k time trial.
Her team-mate Ruairidh Brown claimed the first gold medal of the Games, winning the men’s 15k road race in 24 minutes 15 seconds.
The gymnastics team won 20 gold medals, with Cailiegh Quail from Jersey and Scotland’s Georgia Carslaw both taking five apiece.
In the table tennis competition, Bournemouth twins Alistair and Duncan Feltham won bronze in the men’s doubles, while Duncan also won silver in the singles.
There was also success in athletics, badminton, judo and swimming.
“This has been a very special two weeks for us and our athletes,” said Special Olympics GB CEO Karen Wallin.
“From a Prime Minister’s Downing Street GB Team reception; to winning the historic first gold medal of the 2014 Special Olympics European Games; to athletes performing at their personal best; it is hard to quantify the huge success of this brilliant Belgium experience.
“The performances, passion and endeavour of our athletes, coaches, families, supporters and friends has hit new heights and has to be seen to be believed. This has been a festival of sport, joy and human spirit.
“Our athletes will remember these experiences, together with the fun and friendships they have enjoyed, for the rest of their lives.”
