Works & Achievements

Construction of the Port of Ostia (beginning of works) (37–41 AD)

Caligula initiated the first studies to expand the port of Ostia, a project later taken up and completed under Claudius. This initiative reflects a genuine concern for Rome's grain supply.

Completion of the Temple of Augustus (37 AD)

Caligula had the temple dedicated to his great-great-grandfather Augustus completed and consecrated, thereby affirming the dynastic continuity of the Julio-Claudian line and his own imperial legitimacy.

Construction of the pontoon bridge across the Bay of Baiae (39 AD)

A floating bridge stretching over five kilometers was built across the Bay of Baiae — a remarkable feat of engineering, even if it served only a single spectacular crossing. It illustrates Roman engineering's ability to carry out large-scale temporary constructions.

Extension and reform of the Circus Maximus (37–41 AD)

Caligula had the Circus Maximus enlarged and adorned with new ornaments, continuing the imperial tradition of grand beautification projects in Rome and of popular entertainment.

Transfer of the Vatican Obelisk (37 AD)

He had the Egyptian obelisk moved from Heliopolis to the circus on the Vatican Hill, on the very site where St. Peter's Square stands today. This obelisk is still visible in Rome to this day.

Anecdotes

Caligula's nickname comes from the small military sandals (caligae) he wore as a child in the legionary camps of his father Germanicus. The soldiers adored him and affectionately called him by this name — a nickname that stuck with him for life, even though it annoyed him once he became emperor.

During a campaign in Germania and Britain, Caligula allegedly ordered his soldiers to collect seashells on the shore of the English Channel as 'spoils of the Ocean' — symbolic plunder from a victory over the sea itself. This episode, recorded by Suetonius, illustrates the growing eccentricity of his reign.

Caligula had a floating bridge more than five kilometers long built across the Bay of Baiae, between Puteoli and Baiae, so he could cross it in a chariot while wearing the breastplate of Alexander the Great. According to Suetonius, he staged this feat to defy the astrologer Thrasyllus, who had predicted he had as much chance of becoming emperor as of riding a horse across the bay.

Several ancient sources report that Caligula appointed his horse Incitatus as a priest and was considering making him a consul — a sign, to his contemporaries, of his utter contempt for republican institutions. Modern historians tend to see it instead as a deliberate provocation aimed at the Senate.

After a serious illness in 37 AD, which struck only a few months after he came to power, Caligula's behavior changed radically according to ancient sources. He began to believe himself a living god, demanded worship in his honor, and had his statue installed in temples — including the Temple in Jerusalem, triggering a major crisis in Judea.

Primary Sources

Life of Gaius Caligula — The Twelve Caesars (c. 121 AD)
He had lived at first in poverty and restraint; then, having become emperor, he changed so completely that people said of him there had never been a better slave nor a worse master.
Annals, Book VI (c. 117 AD)
Germanicus was of singular beauty, of proven valor, and though he died in the flower of his age, he was celebrated for his glory, and even more celebrated for his untimely death.
Roman History, Book LIX (c. 229 AD)
He did all manner of senseless and cruel things, whether out of pride, anger, natural desire for pleasure, or mere chance.
Embassy to Gaius (Legatio ad Gaium) (c. 40–41 AD)
He was convinced he was a god and relied upon his own divinity, despising all other human beings as infinitely inferior to him.

Key Places

Antium (Anzio, Italy)

Coastal town in Latium where Caligula was born in 12 AD and where he owned an imperial villa. He returned there regularly and held a particular fondness for the place.

Palatine Hill, Rome

The hill in Rome where the imperial palace (Domus Caesaris) stood, Caligula's primary residence. It was here that he was assassinated during the Palatine Games on January 24, 41 AD.

Baiae (Bacoli, Italy)

A famous seaside resort on the Bay of Naples where Caligula had his renowned pontoon bridge constructed — stretching over three miles — which he crossed in a chariot. The site stands as a symbol of the extravagance and eccentricities of his reign.

Lake Nemi (Nemi, Italy)

A volcanic lake in the Castelli Romani hills where Caligula had two enormous pleasure barges built, rediscovered in the 20th century. These ships, destroyed during World War II, stand as testament to the extraordinary luxury of his building projects.

Capo Miseno — Rhine (Germanic frontier)

The Rhine region where Caligula spent his childhood in the military camps of Germanicus, growing up among the legions. It was here that soldiers gave him his nickname, a sign of the deep affection they felt for him.
