Inside the main doors is a portico (a long hall) which runs across the front of the building and has five doors leading into the basilica. Its has a long curving roof decorated with gold. The light that comes through the doors shines on the beautifully patterned marble floor. At each end of the portico, set between columns, is a statue of a figure on horseback. They are Charlemagne sculpted by Cornacchini (18th century) to the south and Emperor Constantine by Bernini (1670) to the north. Maderna's last work at St. Peter's was to design a sunken crypt called the "Confessio" under the dome, where people can go to be nearer the burial place of the apostle. All around its marble handrail are 95 bronze lamps.
