GREAT PIECE OF ARCHITECTURE

The Pantheon, built by the Romans in 118 AD, is one of the most fascinating piece of architecture ever. Not only does it houses the largest concrete dome that is not reinforced till this date but its manipulation of sunlight into the interior of the building to achieve certain effects at specific dates must require extreme precision. And to think of the mathematics behind the structural support and the limitation of materials and machinery back then, this is undeniably a great piece architecture.
