St. Peter's Basilica, Rome, Vatican (UNESCO)
St. Peter's Basilica in Rome. It is built in late Renaissance style and is one of the largest churches of the world. Construction took 120 years. It started on April 18, 1506 and was completed in November, 18 1626. Right below the main altar is the burial site of Saint Peter, one of the 12 apostles and first bishop of Rome.
I have visited this cathedral myself a few years ago, and I was absolutely impressed by the size and the beauty.
The beautiful card was given to me by Mrs. Anne Loeffler who received it from friends.
