Rome Before the Doors Open
There is no original thing left to say about Rome at midday. There is quite a lot left to say about Rome at half past six.
What the early city looks like
The famous squares are, for about ninety minutes, functional spaces rather than attractions. Crates being unloaded, shutters going up, people crossing them on the way to work without looking at anything. The fountains are running to nobody.
The light in that window is the best of the day, low and warm and coming in sideways between buildings, and it is the only time the monuments can be looked at rather than photographed around. You can stand in front of the Pantheon with maybe a dozen other people.
By nine it is over. Not gradually, either. The change happens across about twenty minutes as the first groups arrive, and the same square becomes somewhere you move through rather than somewhere you stand.
The route
I start across the river and walk in, because arriving on foot over a bridge is a better introduction than emerging from a metro station. Then a loop through the centre that takes in the major squares in the order that keeps the sun behind me, ending at a bar for the first coffee of the day around eight.
The whole thing takes about two hours at a genuinely slow pace with plenty of stopping. It costs nothing, requires no bookings, and is the part of every Rome trip I have taken that I would keep if I could only keep one.
Then the day starts properly: a timed entry somewhere at opening, a long lunch, and the afternoon written off entirely, which is the correct way to spend an afternoon in Rome.
The cost, honestly stated
You have to get up at half past five, and if you are the sort of traveller who wants a late dinner as well then something has to give. In practice I lose the late evening on the days I do this, and it is worth it.
It also does not work for the ticketed interiors, which are on their own schedule regardless of how early you are up. The early walk is for the outdoor city, the squares and the streets and the bridges, and the ticketed sites still need the same booking discipline as everyone else gets.
What it buys is a version of the place that most visitors never see, in a city where nearly everyone leaves with the same photographs. That trade seems obvious to me now, but it took three trips to work out.
