- Pantheon's pronaos -

To enter, we cross the pronaos with its imposing granite column forest. There are sixteen, monoliths, more than 14 metres high, some grey others in pink granite from Aswan, the latter brought from ancient Egypt by transport that would be considered exceptional even today.

The Bronze door at the end of the columns is just as impressive in size, 7 metres high, a real record for the times.
