Fort

History

Fort of Santa Cruz is a sixteenth-century Portuguese fortification in Horta, Portugal, built to defend the harbour entrance and the southern approach to Horta Bay on Faial Island in the Azores. It formed part of a coastal defence system that also included the Fort of Bom Jesus at the mouth of the Ribeira da Conceição and the Fort of Greta on Monte da Guia. Standing at the edge of the historic centre, the fort protected shipping and the settlement during a period when the Azores faced attacks by pirates, privateers, and foreign military forces.

Planning and construction

Concern about the islands’ vulnerability grew during the mid-sixteenth century. Military engineer Bartolomeu Ferraz warned the Portuguese Crown that Faial and other islands needed stronger port defences to protect ships returning from Africa, India, and Brazil. During the reigns of John III and Sebastian, and the regency of Cardinal Henry, later king of Portugal, military architect Tommaso Benedetto reorganized Faial’s defences in 1567. He argued that the islands could be protected by concentrating forces at ports and anchorages under municipal responsibility.

The fort was planned in 1567 as the Castelo de Santo António at the place of the Cross, a name associated with the chapel within its walls. An artillery company was stationed there, while a royal order directed Luís Gonçalves, the director of Public Works, to assist with the completion of works on Faial and São Jorge. The fort’s position on a rocky projection at the harbour edge allowed it to control approaches from the sea and support the defence of Horta.

War and foreign attacks

After the Battle of Salga in 1581, Faial’s coastal defences were strengthened. Existing works were repaired and new battlements were constructed. The following conflict formed part of the Portuguese succession crisis and the Iberian Union, the period from 1580 to 1640 when Portugal and Spain were ruled by the same Habsburg monarchs. In 1583, a Spanish armada commanded by Pedro de Toledo landed troops near Pasteleiro, defeated the defending regiment, and captured Captain-major António Guedes de Sousa at the fort’s gates before executing him. A Spanish garrison was later recalled to Terceira after local inhabitants protested that they could not support or house the occupying force.

On 6 September 1589, an English fleet commanded by George Clifford, 3rd Earl of Cumberland, entered Horta harbour. The fleet captured an Indian carrack and seven other ships before attacking and sacking the settlement. Seven soldiers, the vicar, and Captains Gaspar Dutra, Tomás Porrás, Domingos Fernandes, and João Francisco defended the fort. The attackers removed artillery from the island, burned buildings within the fort, and left the repaired fortress with too few guns for its intended defence.

In August 1597, during the campaigns of Robert Devereux, 2nd Earl of Essex, Walter Raleigh and his men attacked and sacked Horta and set the settlement on fire. With the fort’s artillery reduced, the garrison could mainly prevent ships from landing troops. These attacks demonstrated the continuing exposure of Faial’s principal harbour during the late sixteenth-century Anglo-Spanish conflict.

Garrison, decline, and nineteenth-century conflict

After 1640, the fort began to fall into disrepair. It nevertheless continued to house and garrison small numbers of troops from Horta’s garrison from 1650 until the second half of the twentieth century. Captain James Cook gave an unfavourable description of its condition when he visited Faial in 1775.

When John Bass Dabney, the United States consul general for the Western Islands, arrived in 1805, the fort extended into the harbour. During the War of 1812, Dabney became involved in the events surrounding the destruction of the American privateer General Armstrong in Horta Bay. He advised the vessel’s captain to remain within range of the fort’s guns, hoping that the Portuguese garrison would fire on British forces. The fort did not intervene. The British attacked and burned the vessel, while the fighting damaged houses in Horta and caused deaths and injuries. A dispute over Portugal’s responsibility continued for 36 years.

The Portuguese Liberal Revolution began in 1820 as a movement to establish a constitutional monarchy and led to conflict between constitutional and absolutist forces. During the revolution, the fort fired salvos after local leaders were persuaded to adopt the liberal system. In November 1825, forces loyal to Peter IV, the constitutional monarch who opposed his absolutist brother Miguel, landed at night and seized the fort. They were captured by the following morning. The wider constitutional conflict, known as the Liberal Wars, ended in 1833 with the abdication of Miguel I.

Protection and twentieth-century conversion

Ownership passed to the Câmara Municipal of Horta in 1927. The municipality intended to demolish the fort for a planned coastal avenue, while other proposals called for its stones to be moved to Monte da Guia, for the fort to be preserved or rehabilitated, or for a tunnel to be built beneath it. Lack of funds prevented the demolition. The fort was classified as a national monument by decree no. 36,383 on 28 June 1947.

A project directed by the Directorate-General for Buildings and National Monuments converted the fort into accommodation within the Pousadas de Portugal network, a Portuguese programme for adapting historic or architecturally important buildings for state-associated lodging. The establishment officially reopened as a hostel on 9 August 1969, following a conversion designed by architect Alberto Cruz. The work preserved the defensive exterior walls and the chapel while substantially changing the historic interior. Since then, the site has also been known as the Pousada de Santa Cruz, Pousada de Horta, and Estalagem de Santa Cruz. In 2004 it began operating under the Pousadas de Charme designation, with its official inauguration held on 23 September.

Fortification and harbour setting

The fort originally occupied a rocky shoreline projecting into Horta Bay, with a narrow strip of sandy beach on either side. A small dock along the southern lateral wall served as the Cais da Alfândega, or Customs Wharf. The pentagonal fortress covers approximately 3,650 square metres and is built mainly of basalt and tuff, a soft volcanic stone used especially for the battlements and bartizans.

A bastion, a projecting section that allows defenders to fire along adjoining walls, protects the sea-facing approaches together with two bartizans. Bartizans are small projecting defensive turrets or sentry structures, usually placed at a corner or high point. Two further bastions stand at the northwest and southwest corners, facing inland and defending against attacks from the land. Together, these elements shaped the fort’s response to both harbour and terrestrial approaches.

Entrances and internal buildings

Landward and harbour entrances

The principal entrance lies on the west side, facing Rua Vasco da Gama. A large portal bearing a coat of arms marks the landward approach. A later harbour-side entrance takes the form of a narrow doorway followed by a rounded passage cut through the walls, opening onto the fort’s esplanade.

Garrison buildings

The original plan included a commander’s house, barracks, a powder magazine, storehouses, a bastille, a kitchen, and other dependent buildings. At the fort’s greatest defensive capacity, it mounted 20 artillery pieces and provided banquettes, raised firing steps, for a fusilier garrison. These military installations supported the fort’s role as both an artillery position and a base for troops assigned to the defence of Horta.

Chapel of Santo António

The Chapel of Santo António stands along the southern wall. It is a simple, semi-rectangular basalt building painted white, with exposed stone used for its cornices, door and window frames, and base. Its interior was decorated with azulejos, glazed ceramic tiles widely used in Portuguese architecture, and served the local garrison. The chapel remains part of the preserved historic fabric of the fort.

Adaptation as accommodation

The twentieth-century conversion reorganized the former garrison barracks and surrounding spaces for accommodation. It created 28 rooms, two suites, a restaurant with an esplanade, a bar, conference and reading rooms, and a swimming pool. This remodelling changed the historic interior substantially while retaining the defensive exterior walls and Chapel of Santo António, allowing the fort’s military outline and religious building to survive within its later use.
