The ancient community of Wat Koh is intriguing with its colonial-style Western architecture blended with Chinese influences, showcasing a unique Thai-Chinese cultural community. It features an old market, a late Ayutthaya period ubosot (ordination hall), and a Chinese shrine from the early Rattanakosin period, making it one of the oldest communities in Phetchaburi, rich in arts and culture unlike anywhere else. Wat Koh serves as a central hub for the community, strongly embodying the faith and unity of its people. This is largely supported by the local population who generously contribute in various ways, bolstering and sustaining the community. It is a gathering place for merit-making activities and events that reflect the vibrant life of the villagers, comprising not only Thai residents but also a diverse mix of cultures.
