Saint Peter's Square was created so that more people could be in the presence of the Pope and was named after Saint Peter, one of Jesus's apostles.

Why does the Pope change his name ?
Why the name change? While there doesn’t appear to be a written rule barring Popes from using their real names, it’s been de facto Papal law since the mid-16th century to switch. Currently, it’s the very first question the new Pope is asked after being elected, while still ensconcedin the Sistine Chapel.
The practice of name-switching appears to have started in 533, when a Pope with a pagan name–Mercurius–was elected. Having deemed that unsuitable for obvious reasons, he switched to John II. Between his and Marcellus’s reign, some Popes kept their given names, and some didn’t.
I was always under the impression, it was because Jesus Changed Peters name from Simon??? I'm pretty sure they taught that in Catholic school when I was in grade school.
