About us
The one world foundation supports targeted educational projects in Sri Lanka. With its Free Education School in Ahungalla, it makes possible cost-free education and vocational training for children, young people and adults.


When Kathrin Messner and Josef Ortner (who passed away on 30 March 2009) visited Sri Lanka in 1983, they were in search of a second location where they could gain new experiences, in addition to those that their life in Vienna and their work with contemporary art (museum in progress) already provided them. By chance, they found a plot of land and built a house – an inspiring meeting place for artists and friends. Over the years, the Ayurveda Guesthouse & Resort Bogenvillya, the Art & Literature Programme, and the Free Education School – the core of the one world foundation – arose from this basic idea.

The one world foundation is based on three pillars: the educational project the Free Education School, the Ayurveda Guesthouse & Resort Bogenvillya and the Art & Literature Programme. The foundation supports targeted educational projects in Sri Lanka. The project most dear to founder Kathrin Messner is the Free Education School for more than 1,100 children, young people and adults in Ahungalla, which is financed mainly by the income generated by the Ayurveda Guesthouse & Resort Bogenvillya.

The one world foundation supports a form of tourism based on mutual understanding and fair exchange. It sees itself as a communication centre which promotes dialogue between guests and locals. Through joint celebrations and the close cooperation between the guest house and the school, a sense of belonging is developed, which transcends ethnic and religious boundaries.

The one world foundation also creates space for dialogue and inspirational encounters. Within the Art & Literature Programme (“Art & Residencies”), a place for study is available to artists and writers at the Ayurveda Guesthouse & Resort Bogenvillya.

The founders of the one world foundation, Kathrin Messner and Josef Ortner (who passed away on 30 March 2009), were inspired by the so-called “social sculpture” of the artist Joseph Beuys. He advocated an extended concept of art, which, in addition to materially tangible work, also encompasses human, society-altering action.
