Many view the Parthenon in Greece as the finest example of ancient Architecture especially in the Doric Order.

Explanation:

As a monument with more than 2,000 years of history, the building was made from pure marble and had a number of beautiful sculptures. Over the years, the building has been used as a mosque, a church and even an ammunition depot.

It directly inspired the Romans and eventually the architects of the Renaissance. The building's style, columns and workmanship still inspires people int he 21st century.
