The Sistine Chapel is in the Vatican City. The chapel was commissioned by Pope Sixtus IV in 1475. It was designed to be the Pope’s Chapel and the site of papal elation. The architect was Giovanni dei Dolci. The frescoes on the ceiling, collectively known as the Sistine Ceiling, were commissioned by Pope Julius II in 1508 and were painted by Michelangelo. They depict incidents from the Old Testament. The Sistine Chapel is a rectangular brick building with six arched windows on each of the two main (or side) walls and a barrel-vaulted ceiling.
