The history of Belém Tower is the history of Portugal's golden age. Built between 1514 and 1519, the tower was commissioned by King Manuel I as part of a new defensive system to protect the entrance to Lisbon's harbour. Designed by military architect Francisco de Arruda, it stands as a monument to the Age of Discovery, serving as both a fortress and a grand ceremonial gateway for the explorers setting sail for the unknown.
The Age of Discovery and Construction
In the late 15th century, King John II initiated a plan to defend the Tagus estuary, but it was his successor, King Manuel I, who saw the project through. The tower, officially the Tower of St. Vincent, was built on a basalt outcrop in the river. It replaced a heavily armed ship that had previously guarded the harbour. Architect Francisco de Arruda, who had experience building fortresses in Morocco, blended military innovation with the ornate Manueline style, incorporating Moorish influences like the delicate watchtowers.
Key Architectural Features
The structure consists of two main parts: a four-storey tower, standing 30 metres (about 100 feet) high, and a modern, polygonal bastion with cannon embrasures. The entire building is made of local lioz limestone and is lavishly decorated with symbols of Portugal's power:
- Armillary spheres: A personal emblem of King Manuel I and a symbol of celestial navigation.
- Crosses of the Order of Christ: A nod to the military order that financed many of the voyages.
- Carved stone ropes: A common maritime motif that encircles the building.
- The Rhinoceros Gargoyle: A unique carving inspired by the first rhino seen in Portugal, which arrived in 1515.
From Fortress to Prison to Lighthouse
Belém Tower's primary defensive role was short-lived. In 1580, Spanish forces captured the tower during the conflict that led to the Iberian Union. Over the following centuries, its function evolved. By 1655, it was being used as a customs post, collecting taxes from ships entering the harbour. During the Peninsular War in the early 19th century, French troops were quartered there. It also served as a political prison, its lower levels sometimes flooding with the tide. In 1865, a lighthouse was installed on the terrace to guide ships, a role it held until the mid-20th century.
Restoration and World Heritage Status
By the 19th century, the tower had fallen into disrepair. The Romantic movement sparked a renewed interest in the nation's past, leading to restoration efforts in the 1840s under King Ferdinand II. This work added some Neo-Manueline decorative elements. More significant conservation projects began in the 1940s. In 1983, its global importance was formally recognised when UNESCO declared it a World Heritage Site, alongside the Jerónimos Monastery. Today, it stands as one of the most iconic symbols of Lisbon and Portugal, attracting hundreds of thousands of visitors each year.
