The two colossal holy-water stoups, which stand on either side of the nave of St Peter's Basilica, give a good sense of the sheer size of the church. The four cherubs that hold up the two stoups are each six feet tall.

The holy-water stoups (acquasentiere), which take the form of elaborately ornate shells, were commissioned by Pope Benedict XIII (r. 1724-30) and designed by Agostino Cornacchini (1686-1754). The shells of yellow marble are the work of Giuseppe Lirone, while the chubby cherubs were carved by Francesco Moderati and Giovanni Battista de Rossi.

St. Peter’s Basilica is the largest church in the world. It stands above the spot where St Peter is thought to have been buried. The basilica is the second church to have been erected here; the first was built by Emperor Constantine the Great (r. 306-337) between 324 and 329.
