Despite the limited number of peace museums around the world, there exists an essential role for existing peace museums to promote a culture of peace and peace education. The purpose of this article was to introduce the origins, rationale, scope and work of the Tehran Peace Museum in Iran. The concept of the museum is to facilitate peace education and develop peaceful environments drawn from the personal experiences of war survivors. The museum encompasses exhibitions about the horrors of chemical and nuclear warfare and is balanced with awareness programmes, bridge-building dialogues, connections with other peace museums and a comprehensive peace education programme catering for younger and older members of society. It offers the space and opportunity for a community of learning within the museum and welcomes fresh ideas and initiatives from visitors and volunteers. The Tehran Peace Museum is unique in its body of volunteers, men and women who have been directly affected by chemical weapons. They are involved in the Veterans Voices of Peace Oral History Project and actively voice the need for creating peaceful societies in today's world.
