St. Peter's Basilica Clock
(At the top of the facade of St. Peter's Basilica, left side,
above the Arch of the Bells)

There are two clocks at the extremes of the facade of St. Peter's Basilica at the top and are the work
of G. Valadier.  They were installed in 1786.  The one on the left side (shown here) displays the time in Rome
and strikes on the quarter hour, half hour, and on the hour on six bells.  The main bells have a 6-1/2-foot
diameter and a circumference of 24.6 feet each, and weighs 10 tons.  The clock on the right-hand side of the top
of the facade displays Greenwich Mean Time.
