St. Peter's Square in Vatican City was redesigned in the 17th century by Gian Lorenzo Bernini. The redesign included a long elliptical plaza centered around an Egyptian obelisk, with four rows of columns defining the entrance to St. Peter's Basilica. The symmetrical plaza allows large numbers of people to gather and see the Pope give blessings from the basilica's central balcony. The space balances constraints of existing structures with Baroque design principles to dramatize the approach to the basilica.
