The largest Christian church in the world is the most remarkable legacy of Houphouet-Boigny. Although it doesn't seat nearly as many worshippers, it is structurally larger than St. Peter's Basilica in the Vatican City (after which it was modeled), with a greater surface area and higher dome. As a condition of his attendance at the basilica's consecration, Pope John Paul II insisted that a hospital be built nearby, and he laid the cornerstone for it during his visit; the stone still stands alone.
