Heritage, both cultural and natural, has been with us humans since prehistory and is highly valued for various reasons (e.g., spiritual, economic, aesthetic, historical, and social significance) (Lipe 1983). It thus deserves protection, respect, and continuation. Thailand is rich in cultural heritage, both tangible (historic places, archaeological sites and landscapes, ancient monuments and objects) (Figure 1) and intangible (such as performing arts, indigenous knowledge about nature and society, social practices, traditional crafts, and language) (Figure 2). I am therefore interested in how heritage can be meaningfully sustained and equally beneficial to the people of Thailand. Although heritage is valuable to all kinds of people in societies, the management of heritage is often limited to those who are considered “specialists” or “experts” in specific fields (such as archaeology, art history, architecture, history). These people tend to interpret what they think they know about heritage in their own ways and languages to the public. Here I define “interpretation” as communicating with various audiences using different methods, strategies, actions, and concepts to convey particular messages. Successful interpretation involves various techniques, tools, ideas, and so on and enhances understanding of heritage (see for example Staiff 2016; Swain 2007; Tilden 1977). Although Thailand’s rich cultural resources are critical for the country’s development, public interpretation of cultural heritage at heritage sites (such as museums, historical parks, national parks, ancient monument complexes, and historic towns) in Thailand receives relatively little academic or research attention. Increased public interpretation of cultural heritage promotes better understanding, appreciation, and protection of heritage.
