Romblon is an island province in MIMAROPA, scattered across a group of islands between Luzon, Visayas, and Mindoro in the Sibuyan Sea. Its three main islands—Romblon, Tablas, and Sibuyan—have distinct characters. The province is best known for its marble, which has earned it the name "Marble Capital of the Philippines". The province's modest size belies its geological and cultural distinctiveness.
The Marble Province
Romblon is the country's second-biggest provincial marble producer after Bulacan, and the Mines and Geosciences Bureau estimates its marble reserves at about 150 million metric tons. The stone comes in white, green, pink, red and black. Craftsmen on the island work it into floor tiles, statuary, furniture, and decorative objects. Common products range from small gifts to furniture, baptismal fonts, tiles, balusters and marble chips.
Sibuyan Island, the easternmost of Romblon's main islands, contains Mount Guiting-Guiting (2,058 meters). Its steep slopes and jagged peak have earned it a reputation as one of the most technically challenging climbs in the Philippines. Mount Guiting-Guiting Natural Park protects about 157 square kilometers of forest around it.
The 2024 census counted 302,824 people in Romblon. Its 17 municipalities are spread over three main islands and many smaller ones: nine towns on Tablas, the largest island; three on Sibuyan; and five island municipalities, including Romblon town, the capital.
