The cathedral was fortified specifically to withstand potential Moorish attacks during the 12th century.
The main altarpiece is a significant Renaissance work crafted by Flemish artists Olivier de Gand and Jean d'Ypres between 1498 and 1508.
The interior walls are decorated with approximately 50,000 Hispano-Moorish tiles, representing one of the largest such collections in Portugal.
Construction began in 1139, shortly after the Battle of Ourique, under the guidance of Master Robert, a French architect.
The cathedral's cloister, built during the reign of King Afonso II, is recognized as the first major Gothic structure in the Iberian Peninsula.
Its name 'Sé Velha' distinguishes it from the 'Sé Nova' (New Cathedral) built by the Jesuits in the 16th century.
The cathedral has played a central role in the traditional Coimbra academic festivals, known as the Queima das Fitas.
It was classified as a National Monument in 1910.
The Old Cathedral of Saint Mary of Coimbra is one of the most significant examples of Romanesque architecture in Portugal, dating back to the 12th century. Constructed during the Reconquista, its fortress-like appearance features thick walls and narrow windows designed for both religious and defensive purposes. The structure was commissioned by King Afonso Henriques and incorporates a blend of Islamic and European artistic influences. Visitors can observe the transition between early Romanesque stone masonry and later Gothic decorative elements. The interior is noted for its Renaissance-era altarpiece by Flemish sculptors and extensive collection of medieval azulejos. It served as the primary cathedral of the city until the 18th century when the Episcopal seat moved to the New Cathedral. The building retains its original cloister, which is considered one of the earliest Gothic constructions in the country. It remains a functional religious site while serving as a primary historical monument for Coimbra.
The cathedral courtyard offers the best perspective of the building's robust Romanesque towers against the sky.
Wear comfortable, flat-soled shoes to navigate the original, uneven stone floors and steep surrounding streets.
Allow extra time to explore the cloister, as it contains several medieval tombstones and architectural details often missed by casual visitors.
Visit during the shoulder seasons to avoid the heat and the peak crowds of the academic festival periods.
Avoid attempting to drive to the cathedral, as the streets in the old town are extremely narrow, steep, and restricted to residents.
Maintain a quiet tone appropriate for a place of worship and ensure shoulders and knees are covered.
