The carved facade
Pilasters, scalloped niches and statues worked in local stone β morning light turns the whole west front into a relief map of Baroque ornament.
Gleaming-white Portuguese Baroque from around 1601β1610, a five-minute walk from the fort β inside, a carved wooden interior that stops people mid-sentence.
St. Paul's was raised by the Portuguese Jesuits between roughly 1601 and 1610, on the site of an earlier chapel, in the years when Diu's whitewashed churches were the visible face of Estado da Γndia. What you see today is a textbook Baroque church in Indian disguise: a florid, carved facade of local stone, twin towers, and β the real knockout β an interior of gilded, intricately carved wood.
Its reputation travels. Architectural guides routinely call it one of the finest churches of its type in Asia, and Diu's preservation of Portuguese church architecture is exactly why heritage travelers make the trip at all. Photographers come for the facade's shadow-play; everyone else stays for the altar.
Three things to look for, in the order your eye will find them.

Pilasters, scalloped niches and statues worked in local stone β morning light turns the whole west front into a relief map of Baroque ornament.

A dark, gorgeous nave where light falls on gold leaf and carved wood β the reason this church is called one of the finest of its kind.

The church fronts a quiet square with palm shade β sit a few minutes and watch daily life pass a building older than most countries.
Do Fort β Naida Caves β St. Paul's in one loop of about three hours, then wander the old town's other churches (St. Francis of Assisi, St. Thomas) on foot. Modest dress applies at each. Full plan in the 2-day itinerary β
It functions as a parish church and hosts services β partly why its interior survives so well. Visitors are welcome outside service times; be quiet, switch off flash, and dress modestly.
Hours vary with the parish calendar and season; a common pattern is 9amβ6pm with a mid-day break. Confirm locally or via the tourism office (02875-252653) on your dates.
Hand-held, flash-off photography is generally tolerated, but rules can change β ask the caretaker. The exterior needs no permission and photographs best in morning light.
