And Stratigraphy will be the next hard thing!!

Maybe stratigraphy can be used to date houses made of rock

@Christian

Sewer grates are commonly stamped with the year of manufacture, which can give you the approximate age of the neighbourhood.
The aluminum spacers within thermal-paned windows usually will have the year of production printed or stamped on it, which can at least give an approximate date of installation.

Thanks! Wish I knew that when I was writing this
