L'Union Estate is an 18th-century coconut and vanilla plantation in the island of La Digue, Seychelles.
Originally established as a 300-hectares plantation in 18th century growing coconuts for copra and oil, vanilla, and other tropical crops, the estate later included the Plantation House (locally known as Grann Kaz), an example of French colonial architecture in the Seychelles, built with hardwood and a thatched roof, which served as the residence of the Rasool and Hossein originally from Persia (today's Iran), who owned the estate for a period. Coconut processing continued until the 1980s using traditional ox-driven mills, and vanilla cultivation required hand pollination due to the absence of natural pollinators. But, later it was the holiday home of former President of Seychelles France-Albert René.
By the end of 2010s, it got preserved as a national monument and tourist site. It includes restored buildings, a cemetery with early settlersâ graves, a copra kiln, vanilla plantations, giant tortoises, and access to Anse Source d'Argent. In 2017, the government introduced a scheme to share estate ownership with La Digue residents, retaining 51% and selling 49% to locals. By 2022, the estate became part of an initiative to supply fresh produce and meat to residents and tourist establishments.
