Coimbra — Inês's Posthumous Secret

🎭Your Mission

You are a royal archivist serving Peter I of Portugal in 1355, tasked with reconstructing the truth behind the assassination of Inês de Castro.

Your mission leads you to Coimbra'

Unravel the tragic fate of Inês de Castro, posthumous queen of Portugal, through an immersive journey in Coimbra's history-laden streets.

« Inês de Castro, queen after death. »
Anonymous inscription, Inscription on the Fountain of Tears, Quinta das Lágrimas, Coimbra

The story that haunts this land

Your quest begins on the Ponte de Santa Clara, a 440-meter-long structure completed in 1899 by engineer Edgar Cardoso, connecting Santa Clara a Nova to Coimbra's historic center. This bridge, classified as Imóvel de Interesse Público in 2012, replaced an old medieval bridge damaged by floods of the Rio Mondego. It is here, on the riverbank, that the echoes of Coimbra's royal dramas mingle with the murmur of the water. Inês de Castro, a Galician noblewoman, was exiled to this region by Afonso IV, the father of her lover Peter I, before her assassination. The Mondego River was the silent witness to her suffering.

Continue your investigation towards the Sé Velha de Coimbra, the Romanesque cathedral built between 1162 and 1220 under Bishop Miguel Salomão. With its single 33-meter nave and 13th-century cloisters adorned with biblical scenes, this edifice was the site of the coronation of several Portuguese kings, including Sancho I in 1185. The thick walls of the Sé Velha absorbed the prayers and intrigues of the court, and it was in the shadow of these stones that fatal decisions concerning Inês de Castro may have been debated, marking Coimbra's heritage with an indelible imprint.

Your path then leads you to the Pátio das Escolas da Universidade de Coimbra, founded in 1290 by King D. Dinis. This inner courtyard, paved with 18th-19th century iron lintels, once served as student currency. The Porta dos Corros, dating from 1632, opens to the famous Biblioteca Joanina. Designated a UNESCO World Heritage site in 2013 for its criteria ii, iv, vi, this location was the intellectual heart of the kingdom. Here, the jurists and advisors of King Afonso IV certainly deliberated on the threat Inês posed to the royal lineage, in a Coimbra then in full cultural effervescence.

Explore the Jardim da Manga, a private garden laid out around 1550 by Archbishop João Manuel, nestled within the walls of the Mosteiro de Santa Cruz. Its central octagonal fountain, built in 1719, stands 4 meters high with a marble basin. This peaceful place is linked to the legend of the archbishop's ghost, documented since the 18th century. Although post-dating Inês's era, this garden represents the intimacy and secrets that Coimbra's walls have always harbored. Plots and passions have often been forged away from prying eyes, in spaces like this, through centuries and royal dynasties.

Your journey concludes in Praça do Comércio, an 18th-century Baroque square rebuilt after the 1755 Lisbon earthquake, surrounded by commercial arcades and dominated by the Church of Misericórdia from 1764. Before that, you will have visited the Mosteiro de Santa Clara-a-Velha, a Gothic monastery from 1250, and the Quinta das Lágrimas, the site of Inês's tragedy. This exploration of Coimbra's monuments, from the Sé Velha to the romantic 19th-century gardens, will have allowed you to grasp the full extent of the drama of Inês de Castro, a story of love and power that continues to resonate in the heritage of Central Portugal. You will carry with you the memory of a story that has spanned ages, in the heart of this UNESCO city.
