Reminds me of the book Motel of the Mysteries. Satire on archaeology. https://www.amazon.com/Motel-Mysteries-David-Macaulay/dp/0395284252

Not exactly what you asked for, but David Macaulay's Motel of Mysteries might check some of your boxes. It humorously describes from a future archaeologist's perspective the excavation of ancient Motel and environs: https://www.amazon.com/Motel-Mysteries-David-Macaulay/dp/0395284252
Obviously votive, sacred objects. See: MOTEL OF THE MYSTERIES by David Macaulay. Thousands of years in the future archaeologist discover a motel and misinterpret absolutely everything – – hilariously MOTEL OF THE MYSTERIES
