Ponte Sant'Angelo
Ten angels since 1668
Hadrian had the Pons Aelius built to link the city to the entrance of his mausoleum. In 1668 it gained ten angels with the symbols of the Passion, designed by Bernini and carved by his pupils.

1. Dromos and Atrium
12 m long, facing the bridge
Funeral processions entered the tomb by the Dromos, a high vaulted corridor 12 m long in line with the bridge. A large niche at the end of the Atrium once held a colossal statue of Hadrian; only its head survives.

2. The helical ramp
Rises 12 m
The spiral ramp climbs 12 m inside the mausoleum; it is 3 m wide, about 6 m high and lined with fine brickwork. Built for the funeral procession, it was buried for defence from the 6th century and reopened in the 1800s.

3. Hall of the Urns
About 8 m square
The burial chamber kept the remains of the imperial family until the time of Caracalla, in 217 AD. A plaque bears the lines Hadrian is said to have written to his soul; an 1825 bridge by Valadier crosses it.

4. Courtyard of the Angel
Marble angel of 1544
At its centre stands the marble Saint Michael carved by Raffaello da Montelupo in 1544. It stood on the highest terrace for over two hundred years and was removed in 1747, badly damaged.

5. Loggia of Julius II
Facing the Tiber
The loggia over the Tiber has Tuscan columns, and its architrave bears the name of Julius II. The Pope conceived it as a loggia of blessings; payment records put Giuliano da Sangallo in charge of the works.

6. The Treasury room
A chest with six locks
In 1586 Sixtus V placed the papal treasury in this round hall, with precious objects kept in iron chests. The great chest still at its centre opened only with six locks, each entrusted to a different person.

7. Terrace of the Angel
Bronze angel of 1752
It is the highest point open to visitors, with a view of almost 360 degrees over historic Rome. Above it stands the bronze Archangel Michael by Peter Anton van Verschaffelt, unveiled on the summit in 1752.

The round walk
Four corner bastions
The sentries' round walk runs on top of the outer walls and links the four bastions at the corners. Named after the four Evangelists, the bastions were begun by Pope Nicholas V between 1447 and 1455.
