I’ve admired the bold, tree based Olympia-Rafah Mural Project, located in downtown Olympia WA. Olympia is the sister city of Rafah in the Gaza Strip, Palestine. This 4000 square foot mural “seeks to break down barriers to understanding, increase visibility for Palestinian people, encourage imagination, embrace the hope and courage of Rachel Corrie, and bring people together to work in solidarity for justice and liberation for Palestinians and marginalized people everywhere.” The project began in 2006 and involves more than 150 local, national and international groups and individuals. The project’s website is here.
