The customhouse wharf was constructed between 1470 and 1500, following the arrival of settlers to the island; it was initiated by Álvaro Martins Homem to assist the offload of colonists and goods from Atlantic shipping.[1] But, it was only in the 16th century that the primitive customs building was constructed, which was directly linked to the wharf through the city gates.[1]
On 18 January 1831, that decree 34 ordered the reorganization of military structures, resulting in the system of customhouse guards to prevent the trafficking in contraband on the island of Terceira; this was the precursor to the 1st Regiment of Customhouse Guards of Angra.[1] A decree to restructure the guard corp and constitute a corp of Fiscal Guards occurred on 30 November 1846. By 1853, the current building was reconstructed or built.[1]
On 7 December 1864, decree 1 classified the custom house as a first order maritime entrepot, with two first-order delegations on the islands of São Jorge and Graciosa, and two second-order delegations for Praia da Vitória and another in the villa of Topo.[1]
Eventually, on 17 September 1885, the kingdom's guard corp was reconstituted into the Fiscal Guard and the Angra Fiscal District was constituted. The following year, the Independent Company 3 was created.[1]
By the 19th century, the custom houses received steamships transiting the Atlantic, but, due to the depth of the bay, they were required to anchor farther from the docks.[1]
Between 1950 and 1951, the DGEMN, the Delegação das Obras das Cadeias (Prison Works Delegation), the Delegação das Guardas Republicana e Fiscal (Republican Fiscal Guard Delegation) and the Delegação das Alfândegas (Customshouse Delegation) performed work on the site, including repairs to the building, that continued into 1955.[1] Between the 20th and 21st century, conservation efforts and restoration along the customshouse wharf unearthed infrastructures associated with the primitive city of Angra, that included: vestiges of a bastion fortification; a complex water and sewer networks; and three levels of staircases and patios, that were buried by the accumulation of material.[1]
