Excellent game AbsuluteZero - very enjoyable to watch.
Hmm <checks XML> this is right - I must have been thinking of shrines and academies which remain but without culture - I thought there were more exceptions like universities. FWIW another arguable exception is illustrated by Timbuktu here. If you own or capture Stonehenge, the monument remains and continues to give culture. (Well maybe the enemy monument is destroyed and a new friendly one is immediately erected - same effect though.)
Nope, all standard culture buildings are always destroyed, as well as barracks/other military buildings. Everything else has a chance of surviving.
