I believe the old Spanish fort in St. Augustine is mostly coquina shell slabs, coral and lime stone. Stuff lasts!

Actually, coquina is quite soft. It catches cannon balls, vice cracking.
The Castillo is only 500 years old and has had a lot of repairs. The soft coquina erodes too fast to be have been used in the Egyptian monuments. They are just sand stone I believe.

Down in Glen co Georgia a lot of the Buildings use something called Tabby, its cement mixed with sea shells. Really strong stuff.
