Technically, Vatican City is its own country, but one must go through Rome to get there. Built on the Circus Nero and the surrounding cemeteries, the Vatican is the religious seat of Catholicism. The extraordinary basilica of St. Peters, designed by Donato Bramante, Michelangelo, Carlo Maderno and Gian Lorenzo Bernini is built from stones taken from its Roman heritage largely using the Coliseum as a quarry. The floors of the basilica showcase this plundering with its decorative reuse of the prized red porphyry marble among other materials. And it is within this floor that lies this cover which glints in the soft light as it gives access to crypts below. The motif is naturally decorative with a concentric polar array along with an addition of the city-state’s symbol at its center and a nod to the cardinal points or the initials of a Roman girl gone missing not too long ago.
