Hadrian built it between approximately 118 and 128 AD on the site of earlier temples in the Campus Martius district of Rome, and it has served as a temple, a church, a tomb, and a tourist site across nineteen centuries without the structural interruption of abandonment. The dome that spans its interior has not been surpassed in diameter — 43.3 meters — by any unreinforced concrete construction in the two thousand years since it was poured. Whatever Rome&rsquo;s engineers knew, they knew something that took a very long time to recover.</p>
