Central Zone of the Town of Angra do Heroísmo in the Azores: A Unique Blend of History and Culture
The Central Zone of the Town of Angra do Heroísmo in the Azores is a remarkable testament to the rich history and cultural heritage of Portugal's autonomous region in the Atlantic Ocean. This urban center, located on the island of Terceira, has been designated as a UNESCO World Heritage Site since 1983, making it a must-visit destination for history enthusiasts and travelers alike.
Established in 1478 and granted city status in 1534, Angra do Heroísmo, often simply referred to as Angra, played a pivotal role in the Azores' development. Its strategic location made it an essential stopover for ships traveling between Europe and the New World during the Age of Discovery. For four centuries, from the 15th to the 19th century, Angra was the primary port of call in the Azores archipelago.
Two notable fortifications, San Sebastião and San João Baptista, stand as unique examples of military architecture within the Central Zone. These fortresses were built to protect the town from potential invasions and pirate attacks.
The San Sebastião Fortress, constructed in the late 16th century, was the city's first major maritime fortification. Designed in an Italian Renaissance style, it features a bastioned layout with a triangular artillery platform to defend the bay. The San João Baptista Fortress, on the other hand, a massive polygonal citadel covering Monte Brasil, remains one of the most expansive Spanish defensive complexes built outside Spain. Both fortresses have undergone restoration efforts following damage sustained during the 1980 earthquake that struck the Azores.
In addition to its military history, Angra do Heroísmo boasts a significant religious heritage. The Church of São Gonçalo, founded in 1542, it is a masterpiece of Baroque architecture. It is renowned for its 18th-century gilded woodwork (talha dourada), painted ceilings, and intricate tile panels. Another noteworthy religious structure is the Convent of São Francisco. This 17th-century complex houses the Museum of Angra do Heroísmo, which displays artifacts ranging from military history to traditional Azorean costumes, and the Church of Our Lady of Guia.
Beyond its historical sites, Angra do Heroísmo offers visitors a glimpse into the local culture. The town's cobblestone streets, colorful buildings, and lively squares create an inviting atmosphere that encourages exploration. Traditional Azorean cuisine can be sampled at numerous restaurants, featuring dishes such as Alcatra (pot roast) and Dona Amélia pastries.
Today, Angra do Heroísmo continues to thrive as a vibrant community and a popular tourist destination. The ongoing restoration of damaged structures, such as the fortresses and churches, ensures that the town's rich history remains preserved for future generations to appreciate. Whether you are drawn to the town's military past, religious heritage, or vibrant culture, a visit to the Central Zone of the Town of Angra do Heroísmo in the Azores promises an unforgettable experience.

Responses to earthquakes and volcanic eruptions under authoritarian rule: a comparison between fascist Italy and Portugal during the Estado Novo
Authoritarian regimes in Italy and Portugal during the mid-20th century demonstrated both successes and limitations in disaster management, revealing deep-seated continuities in vulnerability and resilience that persist regardless of political context. Despite their authoritarian nature, reactive management styles, and lack of democratic accountability, both Mussolini's Fascist Italy (1922–1943) and Portugal's Estado Novo (1932–1974) effectively handled post-disaster responses and long-term recovery in certain cases. However, larger-scale disasters strained their resources, particularly when peripheral areas were involved. In Italy, the rebuilding of Mascali after a 1928 earthquake showcased successful integration of style and substance, while Portugal's responses to the 1957/58 eruption on Faial and the 1964 Azores earthquake relied heavily on local leadership. The 1969 Algarve earthquake marked a shift, with the regime mounting an effective response without local prompting due to changes in cabinet personnel and priorities.

Post-Pandemic Touristification and Sociodemographic and Residential Vulnerability in Macaronesian Historic Centres: Angra do Heroísmo (Azores) and Vegueta–Triana (Canary Islands)
Post-pandemic tourism growth in UNESCO World Heritage Sites leads to distinct sociodemographic and residential vulnerabilities depending on the depth, speed of change, and local governance capacity. A comparative study of Angra do Heroísmo (Azores) and Vegueta–Triana (Canary Islands) reveals that while both sites experience intensified touristification, its effects differ significantly. In Vegueta–Triana, tourism is linked to space commodification, housing pressure, and weakened residential function, whereas in Angra do Heroísmo, it is associated with heritage-based hotel development and functional revitalization, though concerns about population loss persist. The study used a mixed-methods approach, combining official statistics (2018–2025), accommodation records, and semi-structured interviews conducted between 2024 and 2025, highlighting the nuanced impacts of tourism on historic centers in Macaronesian island spaces.

Original plant diversity and ecosystems of a small, remote oceanic island (Corvo, Azores): Implications for biodiversity conservation
Research on the remote island of Corvo (Azores) reveals significant gaps in biodiversity knowledge, with evidence suggesting eight local plant extinctions and four species previously classified as 'introduced' actually being native. The study used fossil remains—including pollen, charcoal, macrofossils, diatoms, and sediment geochemistry—to reconstruct pre-colonial ecosystems. Findings indicate that up to 23% of pollen taxa represent extinct or misclassified species, highlighting the dynamic nature of Corvo's environment, which shifted from glacial-era open vegetation to Holocene forests before severe human-induced deforestation. This work addresses critical 'Wallacean' and 'Hookerian' biodiversity knowledge gaps, providing a baseline for conservation efforts on islands with profound anthropogenic disruption.

Stochastic simulation of earthquake ground motions for the seismic assessment of monumental masonry structures: Source‐based vs site‐based approaches
Research demonstrates that both source-based and site-based stochastic simulation approaches yield similar predictions for the seismic response of monumental masonry structures. The study, focusing on the 1998 Faial earthquake (Mw = 6.2) in the Azores, simulated ground motion records at four stations using two methods: a source-based stochastic finite-fault approach and a site-based broadband stochastic method. Investigations were conducted on two masonry facades with varying slenderness levels and an existing monumental structure, São Francisco Church, which sustained damage during the earthquake. Findings indicate that even minor discrepancies in predicted damage patterns can lead to significant errors in displacement predictions, underscoring the importance of precise simulation methods for seismic assessment. This study advances understanding of how simulated ground motion records can be reliably used for the protection and analysis of heritage buildings in seismically active regions with limited real data.
