The Sitios association was founded in 2022 by the Swiss Barrier-Free Association, Pro Infirmis and the AccessibilityGuide association. His aim is to coordinate and further develop the range of information on accessibility in Switzerland. The association is based in Zurich, is tax-exempt and not profit-oriented.
Sitios' most important project is the operation and development of Ginto. Ginto finds, collects and shares information about the accessibility of locations.
