The columns left over from the Temple of the Divine Hadrian are perfectly integrated into the modern building - the building of the Chamber of Commerce and Industry. This building looks fantastic! As they would say in modern language, "adaptation of a cultural heritage building for modern use" :)) In the 17th century, the famous architect Domenico Fontana built the papal customs building into what remained of the temple. At the end of the 19th century, the Roman stock exchange was located there. And the current purpose of the Hadrian's Temple is the Chamber of Commerce. Apparently, this is not the last functionality of the ancient temple :))
