The Architect Emperor Hadrian was a genius of building and public projects.

here is an interesting tidbit about Roman building and redecorating during his period:

" With the aid of the architect Decrianus he raised the Colossus and, keeping it in an upright position, moved it away from the place in which the Temple of Rome is now, though its weight was so vast that he had to furnish for the work as many as twenty-four elephants. This statue he then consecrated to the Sun, after removing the features of Nero, to whom it had previously been dedicated, and he also planned, with the assistance of the architect Apollodorus, to make a similar one for the Moon. "

he used 24 elephants to move a colossis of the Sungawd (some say nero's likeness)
