I've started to really like floors.

Another floor.

Not a floor, but an ancient sign for a snack bar.

Floor.

Floor.

One of my favorite floors in the Vatican.

After about hour 2-1/2, I was beginning to feel like this guy.

St. Peter's Basilica

The interior.

Under the white canopy is where the Pope sits during his weekly appearance on Wednesdays.

The Pope's palace is there on there right and on Sundays, he waves from the second window.

St. Peter's with the Sistine Chapel behind it.
