- Pope Francis said building walls to keep immigrants out is "not Christian"
- Critics of the Pope point out that Vatican City has walls
Isn't Vatican City, the Catholic Church's 110-acre sovereign state, surrounded by walls?
"Amazing comments from the Pope -- considering Vatican City is 100% surrounded by massive walls," tweeted Dan Scavino, the Trump campaign's director of social media and a senior adviser.
That's not quite true, though, said several Catholics familiar with the layout at Vatican City.
Yes, the Vatican does have walls, and some are quite large. But anyone can stroll through the Pope's front yard -- St. Peter's Square -- at nearly any time. Only metal detectors stand between the iconic landmark and the millions of tourists who come to see the historic headquarters of the Roman Catholic Church.
In other words, Vatican City may have walls, but the front door is always open, said the Rev. James Martin, a Catholic priest and editor at large at America magazine.
"The fortifications were built a very long time ago," Martin said. "This Pope didn't build them -- and he certainly didn't build them to keep out poor migrants.
To emphasize his point, Martin tweeted a picture of St. Peter's Square.
