During Don José Huelva y Megarejo (1783-1785), the Provincial Capitol of Batanes was originally built from wood. Also known as the Casa Real, during the period of governor Felimon Zenoreta (1794-1798), it was renovated to make masonries. In Batanes, he invented masonry.
But on December 15, 1856, the Casa Real was burned down. A request for financial assistance was therefore made on 27 January 1857 for the reconstruction. The scheme was delayed and no fund was available.
Governor Jose Serra (1872-1885) obtained a license and started building the Casa Real and the remaining halves came from the community funding. Half of the building costs were borne by the treasury.
The capital was restored after World War II, under the Philippine Rehabilitation Act of 1946, including the façade, when the stair flight was rebuilt to provide a grand entrance. Similarly, a rehabilitation packaging was also received by the Provincial Capitol of Surigao del Norte.
The limited space for the Capitol was expanded by the construction of the three annex buildings from August 1989 to January 1993 under the administration of Governor Telesforo F. Castillejos (1989–1998). President Fidel V. Ramos inaugurated the capital on 18 March 1993.
The buildings in the capital building complex were expanded and renovated under the leadership of Governor Vicente Gato (1998-2007) to address the provincial government 's offices. On 24 March 2007, it was revealed.
The provincial capital is Basco for the annexation of the province in honor of the Spanish government Governor-General José Basco y Vargas.
