Portuguese City of Mazagan (El Jadida): A Unique Blend of Cultures
The Portuguese City of Mazagan, now known as El Jadida, is a captivating testament to the rich cultural exchange that took place between Europe and North Africa during the early modern period. Inscribed as a UNESCO World Heritage Site in 2004, this historic city offers a unique blend of Portuguese and Moroccan architectural styles, reflecting the enduring influence of the Portuguese explorers in West Africa on their journey to India.
More to come…UNESCO Description of the World Heritage Site
The Portuguese fortification of Mazagan, now part of the city of El Jadida, 90-km southwest of Casablanca, was built as a fortified colony on the Atlantic coast in the early 16th century. It was taken over by the Moroccans in 1769. The fortification with its bastions and ramparts is an early example of Renaissance military design. The surviving Portuguese buildings include the cistern and the Church of the Assumption, built in the Manueline style of late Gothic architecture. The Portuguese City of Mazagan - one of the early settlements of the Portuguese explorers in West Africa on the route to India - is an outstanding example of the interchange of influences between European and Moroccan cultures, well reflected in architecture, technology, and town planning.
UNESCO Justification of the World Heritage Site
Criterion (ii): The Portuguese City of Mazagan is an outstanding example of the exchange of influences between the European and Moroccan cultures from the 16th to 18th centuries, and one of the very first settlements of Portuguese explorers in West Africa on the route to India. These influences are clearly reflected in the architecture, technology and urban planning of the city.
Criterion (iv): The fortified Portuguese city of Mazagan is an outstanding example and one of the first, representing the new design concepts of the Renaissance period integrated with Portuguese construction techniques. Among the most remarkable constructions of the Portuguese period are the cistern and the Church of the Assumption, built in the Manoeline style at the beginning of the 16th century.

From the high citadels of Pedro Escrivá in Naples to the new Portuguese paradigm of coastal city-fortresses
This study reveals a significant shift in Portuguese military architecture during the early 1540s, marked by the development of low-profile, bulwarked coastal city-fortresses designed to counter maritime warfare. The research highlights how Francisco de Holanda's experiences in Italy, particularly his exposure to Pedro Escrivá's star-shaped citadels and brick construction techniques, influenced the design of Mazagão (El Jadida), the first Modern European city-fortress. Unlike traditional high citadels, these new structures prioritized adaptability to naval sieges, reflecting Portuguese innovations in both military engineering and overseas expansion strategies.

La cittadella portoghese dell’antica Mazagan in Marocco (XVI secolo)
The Portuguese citadel of Mazagan (El Jadida), built in the 16th century, stands as one of the earliest examples of Renaissance military architecture in Morocco. This study reveals that despite its conquest by Moroccan forces in 1769, the site retains significant traces of its Portuguese origin, including a fortress with cisterns, robust walls, and the Church of the Assumption, constructed in Manueline style. By analyzing the architectural characteristics and urban evolution of Mazagan's buildings, the research provides a comparative framework between Portuguese military architecture and contemporary Moroccan styles. The findings highlight the enduring influence of Portuguese design on the site, even after its political transition.

Nutritional and antioxidant potential of Gelidium corneum from the El Jadida coast, Morocco
Gelidium corneum, a red macroalgae abundant along the Atlantic coast of Morocco, particularly around El Jadida, exhibits significant nutritional and antioxidant potential. This study reveals that G. corneum contains high levels of protein (26%), carbohydrates (55%), and lipids (6%), alongside notable amounts of alkaloids, flavonoids, coumarins, and tannins. The algal biomass demonstrates dose-dependent antioxidant activity, effectively scavenging DPPH free radicals. These findings underscore the species' dual value as a sustainable source for agar production and a promising candidate for pharmaceutical, cosmetic, and food industries due to its functional properties and bioactive compounds.

Anatomical and Tissue Study of the Organs of the Marine Gastropod Phorcus lineatus (Da Costa, 1778) from El Jadida Coastline (Atlantic coast, Morocco)
A comprehensive anatomical and histological study of the marine gastropod Phorcus lineatus from El Jadida's coastline, Morocco, reveals detailed insights into its internal and external morphology, as well as cellular organization. This research marks the first such description for this species, providing foundational data essential for future bioaccumulation studies aimed at monitoring pollution health in Morocco's Atlantic coasts. The study employed a year-long collection of specimens from June 2018 to May 2019, followed by macroscopic and microscopic observations, along with histological analysis. Phorcus lineatus was selected as a bio-indicator due to its resilience in polluted environments, limited mobility, and ecological significance in the food chain. The findings enhance our understanding of this species' structural intricacies, paving the way for broader ecological assessments.

Diversidad de hormigas (Hymenoptera, Formicidae) en un área natural vs otra reforestada a lo largo de la costa atlántica marroquí
A high rate of ant endemism (31.57%) was recorded along the Atlantic coast of El Jadida, Morocco, with 19 species identified across two sites: Haouzia's natural scrubland and Chiadma's eucalyptus reforested area. The study found significantly higher ant diversity in Haouzia, with 13 species (Shannon index: 5.9) compared to 11 in Chiadma (index: 3.5), suggesting potential negative impacts of eucalyptus reforestation on local biodiversity. Most species were new records for the region, except Aphaenogaster theryi and Cataglyphis vaucheri. Sampling was conducted using pitfall traps during four campaigns in April–May 2022, highlighting urgent conservation needs for this understudied UNESCO World Heritage Site.

Military borders, political frontiers: settling the Portuguese urban space in North Africa
Portuguese urban expansion in North Africa, spanning from 1415 to 1769, was characterized by the conquest and integration of pre-existing Arab and Muslim cities along the Strait of Gibraltar and Atlantic coasts. Unlike traditional colonial models, these territories were ruled directly by the Portuguese Crown through local captains and governors, with limited hinterland influence beyond city walls. The study reveals a strategic shift in military and political strategies, transitioning from late-medieval to early-modern conceptions around 1500. It highlights two key regions: the northern 'overseas Gharb,' including Ceuta, Ksar Seghir, Asilah, and Tangier, where Portuguese influence was intermittent; and southern cities like Azemmour and Safi, established as suzerainties to block Marrakesh's access to seaports. The research approach combines historiographical analysis with spatial and political mapping to elucidate the complexities of Portuguese territorial control in North Africa.

Hard to Obtain, Hard to Translate: Lime and Earth Construction in Early Modern Portuguese Writings on Architecture and Fortification
Early modern Portuguese writings on fortification reveal a pragmatic approach to construction, favoring time-tested knowledge and practical experimentation over theoretical guidance. A notable finding is the preference for lime masonry over earth filling for ramparts, despite the difficulty in obtaining high-quality lime. Administrative records from Mazagan (1541) provide firsthand accounts of new fortress-building methods, while an anonymous manuscript from around 1579 blends multiple sources with the author's observations, introducing new terms and techniques that pose translation challenges. The study highlights the merging of Vitruvian principles with empirical knowledge, showcasing a blend of tradition and innovation in early Portuguese architectural practices.
