The non-profit association (asbl) was founded in 1975 by a group of volunteers wishing to provide a “family” way of life for adults with intellectual disabilities. At that time, a residential home located in the centre of Liège accommodated a small group of adults with intellectual disabilities. The home was run by live-in volunteers committed by idealism and personal beliefs.
From 1986 onward, small occupational workshops began to be created within the actual home, under the responsibility of one permanent member of staff and a few volunteers. In 1988, the home moved to a rural location.
In March 1995, a second home was opened. A new workshop that could accommodate more people was also built, and an application for recognition by the Agence Wallonne pour l’Intégration de la Personne Handicapée (AWIPH; Walloon agency for the integration of people with disabilities) led to certification as a day centre (SAJA; Service d’Accueil de Jour pour Adultes Handicapés) for 15 people with disabilities, including three places for people receiving Category C benefits.
In 1999, the two homes, Le Murmure and L’Espérance, and the day centre, Le Sénevé, were grouped under a single non-profit association (asbl): L’Arche Aywaille.
In 2014, with the construction of its new homes, the community now supported and accommodated 27 people with disabilities across the four homes.
In 2016, L’Arche Aywaille opened a residential service for adults which could assist and accommodate 13 people with severe disabilities in its new home Le Fil de l’Eau, located in Harzé.
