History of Ko Si Chang

Ko Si Chang, a small island in the Gulf of Thailand, has a rich history that dates back to the Ayutthaya period. It was once an important strategic location for the Siamese Kingdom due to its proximity to the mainland and its sheltered harbors. During the reign of King Chulalongkorn (Rama V) in the late 19th century, Ko Si Chang was developed as a royal retreat. The king used the island as a base for his visits to the area, and he established a summer palace, known as the Phra Chudadhut Palace, on the island.

In the 20th century, Ko Si Chang became a popular destination for both locals and tourists. The island’s historical significance continued with its involvement in the maritime and shipping industries. Today, while the island retains much of its traditional charm, remnants of its royal past, such as the Phra Chudadhut Palace and various temples, still stand as testaments to its important role in Thai history. Visitors to Ko Si Chang can experience both its natural beauty and its historical heritage, making it a unique destination in Thailand.
