The Parthenon
The Parthenon is the most important surviving building of Classical Greece, which is a former temple. Contrary to the gleaming white facade which is often how Greek temples and structures are depicted, the Parthenon was most likely very colourful in its ancient state.
To ensure its stability and to preserve this partially ruined structure, restoration and reconstruction processes have begun. All new reconstruction metalwork uses titanium, a strong, light, and corrosion resistant material.
