How many classical Greek and Roman buildings are still standing today (mostly intact)?
That depends certainly on what you would accept as “mostly intact”. I don’t have any numbers ready, just a coarse guess. The Concordia temple in Agrigento, Sicily, http://www.mlahanas.de/…/…eOfConcordia.html and the Hera Temple in Paestum are among the best preserved temples from classical Greece. Intact Roman buildings in Italy, there may be more (Forum Romanum, Rome). Many bridges, since those were used and maintained. All in all it may be less than hundred that would be as well preserved as the Concordia temple. You may browse here: http://www.antikefan.de/index.php site is in German, but it’s mostly pictures.
