Chanthaburi is famous for its abundance of tropical fruits and as a major center for gem mining, polishing, and sales. The eastern province of Chanthaburi is covered with rich, verdant forests with many scenic waterfalls. The Chanthaburi River flows through the ancient provincial capital. Quiet fishing villages and peaceful beaches are nearby, making Chanthaburi a wonderful and relaxing destination. Chanthaburi, the capital of the province bordering Cambodia to the east, was occupied by the French during the end of the 19th century and French influence can be seen in the architecture of many buildings within Chanthaburi town, including the largest Catholic cathedral in Thailand, attended by a sizable Christian population, many of whom are ethnic Vietnamese, who migrated to Thailand in the 20th century.
