This type of design is attributed to the Galle region, between 1830-1850. Situated on the south-western coastal belt of the island, the centre had intially been under Dutch influence until they were ousted in 1796, when the British East India Company gained autonomy of the Maritime Provinces. By 1802 this became a crown colony and by 1815, with the seizure of Kandy, the whole island was subjugated.
The scalloped edge is a feature inherited from 18th century Dutch Colonial patronage. Some examples can be attributed to cabinet-makers from the fort town of Matara, in the Galle district.
