|The prompt for Week 29: "vintage architecture"|
Old buildings it is, and here's my favorite:
This is the portico of the Pantheon in Rome. It was
rebuilt by Emperor Hadrian in 126 AD, but
the original structure is exactly 2000 years old!
|And it still has the world's largest|
unreinforced concrete dome.
