Chapel of St. Cajetan: the church Italian friars built for a mission that never happened, over a well that may have been a temple

A Old Goa, in India, tre frati teatini italiani, giunti tra il 1639 e il 1640 con l’obiettivo di evangelizzare il sultanato di Golconda, non riuscirono mai a stabilire quella missione e si insediarono invece a Goa, sotto la guida di Pietro di Avitabili, che ottenne l’appoggio del re Giovanni IV del Portogallo. Il re approvò la costruzione di un ospedale nel 1650 e della chiesa nel 1655; i lavori, diretti dagli architetti italiani Carlo Ferrarini e Francesco Maria Milazzo, si conclusero nel 1661. L’edificio, a pianta a croce greca, è una delle poche chiese di Goa dotate di cupola, decorata all’interno con iscrizioni latine tratte dal Vangelo di Matteo; la facciata, in stile corinzio, presenta quattro statue in granito raffiguranti i santi Pietro, Paolo, Giovanni Evangelista e Matteo. Secondo la tradizione popolare, l’edificio fu modellato sulla Basilica di San Pietro a Roma, sebbene alcuni viaggiatori dell’epoca sostenessero invece un modello diverso, la chiesa teatina di Sant’Andrea della Valle a Roma — una questione rimasta dibattuta tra gli storici. Sotto la cupola, su una piattaforma quadrata rialzata, si trova un pozzo coperto, la cui presenza ha alimentato l’ipotesi, mai confermata archeologicamente, che l’edificio sorga sul sito di un antico tempio indù legato alla dinastia Kadamba e alla città preportoghese di Ela. Dal 1986 la cappella fa parte, con altri sei monumenti, del Patrimonio Mondiale UNESCO “Chiese e Conventi di Goa”.

About the Chapel of St. Cajetan

The Chapel of St. Cajetan, in Old Goa, India, was built by three Italian friars of the Theatine order, who arrived in Goa around 1639-1640 hoping to establish a mission in the Golconda Sultanate, an ambition that never materialised; under the leadership of Pietro di Avitabili, who secured the support of King John IV of Portugal, the friars settled in Goa instead. The king approved a hospital in 1650 and the church itself in 1655, with construction, directed by the Italian architects Carlo Ferrarini and Francesco Maria Milazzo, completed in 1661. Built on a Greek-cross plan, the church is one of the few domed churches in Goa, its dome interior decorated with Latin inscriptions drawn from the Gospel of Matthew, while the Corinthian-style facade displays four granite statues of Saints Peter, Paul, John the Evangelist and Matthew. Popular tradition holds that the church was modelled on St. Peter’s Basilica in Rome, though some contemporary travellers argued instead that its true model was Sant’Andrea della Valle, the Theatine order’s own church in Rome — a question that remains genuinely disputed among historians rather than settled. Beneath the dome, on a raised square platform, stands a covered well, whose presence has fuelled the belief, never archaeologically confirmed, that the church occupies the site of an earlier Hindu temple connected to the Kadamba dynasty and the pre-Portuguese settlement of Ela. Since 1986, the chapel has formed part, alongside six other monuments, of the UNESCO World Heritage Site “Churches and Convents of Goa,” and it remains an active parish church today.

History

The Chapel of St. Cajetan’s origins in a failed missionary ambition, redirected into the construction of a permanent church in Goa, reflects the broader pattern of European religious orders adapting their objectives to the realities of colonial-era Asia. The unresolved question of the church’s architectural inspiration, along with the enduring local tradition linking its well to a pre-Portuguese Hindu temple, gives the building a layered, still-debated history that extends well beyond its documented 17th-century construction.

What you see

The church’s Corinthian facade, fronted by granite statues of four saints, opens onto a Greek-cross interior crowned by one of Goa’s few church domes, its interior inscribed with Latin verses from the Gospel of Matthew. Beneath the dome, a covered well set on a raised platform draws particular attention from visitors, its presence at the heart of the church’s ongoing historical mystery.
