In 1988, Marc Huynen visited Finland with his wife. In the tourist documentation he received, he discovered an original map of the country with indications of so-called "open" churches. He inquired and discovered that this idea also existed in England.
Their "Open Churches Trust" published a real collection of open churches, i.e. more than 11,000 of the 16,000 existing ones. This initiative of a network of open churches existed in other countries but not in Belgium.
2007 : Marc Huynen then gathered around him a few people from different professional and philosophical backgrounds but all interested in the project: to open our churches.
Today the network has been deployed in Belgium, the Grand Duchy of Luxembourg and in France (Nord-Pas-de-Calais and in the East) and it is beginning to spread to Burgundy and Normandy.
Open Churches associations have been created and have joined the non-profite organisation Open Churches, generating a vast cross-border network.
