Intergenerational learning is based on processing experiences from one generation to another. However, this process is up to now mostly based on face to face communication neglecting the capabilities of computer supported learning communities. In this paper we describe ACIS (Afghan Community IS), a system that has been designed to support intergenerational learning communities by geographical hypermedia information systems in the area of cultural heritage. ACIS is designed to bring together generations of scientists in cultural heritage management which has been disrupted by the civil war and the Taliban regime in Afghanistan. ACIS has been deployed for a project in the conservation of cultural heritage in Afghanistan to prove the validity of the concepts.
