The notion of a Buddhist museum was supported by 17 countries including Sri Lanka, Nepal, India, Pakistan, Afghanistan, Malaysia, Thailand and Laos. The museum in Sri Lanka is the first international Buddhist museum in the world. The site was the former royal residence of King Wimaladarmasuriya, and the building that was constructed later during the British Rule boasts Victorian-era architecture. The International Buddhist Museum is well worth a visit if you want some insight into the religious history of the country. The extensive list of artefacts on display will guide you through the rise of Buddhism in Sri Lanka.
