Why go
Chanthaburi is a provincial town with a strong character. At weekends, the gem market fills the streets with traders examining sapphires and rubies with magnifying glasses.
The Cathedral of the Immaculate Conception is the largest Catholic church in Thailand, built by a Catholic community with roots going back centuries.
The Chanthaboon waterfront old town has wooden houses, cafés and shophouses along the river.
The town is also a fruit-growing centre, with durian, mangosteen and rambutan farms in the surrounding hills. During the fruit season, there are fruit festivals and roadside stalls everywhere.
The story
The Catholic community in Chanthaburi includes descendants of Vietnamese Catholics who settled here centuries ago.
The French occupied Chanthaburi for some years in the late nineteenth century, leaving traces in local history.
The gem trade developed because of local sapphire and ruby deposits and grew into an international market with traders from many countries.
King Taksin, who restored Thai independence after the fall of Ayutthaya in the eighteenth century, gathered his forces in Chanthaburi; there's a shrine and monument to him in town.
