POTD: Room after Room after Room

From 2018 08 14 Peterhof

Today's photo-of-the-day is from Peterhof, the St. Petersburg palace built by Peter the Great of Russia. It shows a hallway that runs along the length of the palace. Actually, it's not a separate hallway at all. More like a series of doors that connect all the rooms. Walking through them, you go through room after room after room. It's quite unlike modern buildings, like hotels, where the hallway is like a spine and the rooms are all off to the side like ribs. I guess that's because the occupants of the palace owned *all* the rooms so there was no need to keep them separate for privacy as one walks around the palace. Or maybe there's another reason that historical architects might be able to explain.
