The British daily The Guardian recently released its list of the best concrete building in the world. The marvelous Rome-based Pantheon got the gold medal. This beautiful building commissioned by Marcus Agrippa and completed by the emperor Hadrian is one of the best-preserved Ancient Roman constructions, which in the 7th century was converted in a church.

According to The Guardian, "The true moment of genius is the way in which, after a certain amount of harrumphing with Corinthian columns and marble decoration at its lower levels, the design resolves itself into the pure circular oculus at its top, unglazed, which causes a beam of light to rake around the interior like an internalised sun". And it is right that no one has been able so far to reproduce a similar structure.
