Gua Tambun is the largest rock art site in Peninsular Malaysia, and one that I studied for my MA years ago. So I am mighty pleased to urged your support for the Gua Tambun Heritage Awareness Project, run by my colleague Dr Goh Hsiao Mei. (Disclaimer: I am not personally involved with project, but I support it 100%!)
Dr Goh is currently building a public archaeology and outreach programme to help raise awareness and appreciation for the Gua Tambun site in Ipoh, and to empower the people living near the site to help manage it from both a conservation and visitor management standpoint.
She is currently raising funds to develop and conduct school programmes and community workshops and at the time of writing she has met a third of the RM4,300 (about US 1,000) that she needs. You can contribute to her cause on her crowdfunding website, the Gua Tambun Heritage Awareness Project.
