1855–1872
Twenty-four arches, and no iron in them
It took seventeen years. The work was driven by Fr Joseph Grégoire, whom his chronicler calls the apostle of Vadakenkoulam, and the building was engineered by a Jesuit lay-brother named Joseph Bergenthal, whose office the Society's Roman register for 1872 gives in two words: Ædif. eccl., builder of the church. Between them they turned twenty-four arches that carry their own weight, in lime and palm-toddy mortar, without cement, without iron, and without one wooden beam holding anything up. Halfway through, in 1861, the bishop came again, and three thousand Christians were waiting for him on the road.

What this source establishes
Dessal, a Jesuit of the same mission, says only that the church is "unique au monde peut-être" — unique in the world, PERHAPS. The hedge is worth keeping: the mission's own chroniclers never claimed more than that.
