In 71 AD, after several campaigns, the Legio XV ''Apollinaris'' returned to Carnuntum and rebuilt its fortress. While some of the legion fought in
Trajan's Dacian Wars, the main body of the legion remained in Pannonia.

In 117–118 AD, Carnuntum became the permanent quarters of

History of the city
In Roman times, Carnuntum had a history as a major trading centre for
amber, brought from the north to traders who sold it in
Italy; the main arm of the
Amber Road crossed the Danube at Carnuntum.
As , the capital of
Pannonia Superior, it was made a by Hadrian. Its importance is indicated by the fact that
Marcus Aurelius resided there for three years (172–175) during the war against the
Marcomanni, and wrote part of his ''
Meditations'' there. Also
Septimius Severus, at the time governor of Pannonia, was proclaimed emperor there by his soldiers (193),
to replace Emperor
Pertinax, who had been murdered.
In the
Severan dynasty (193–235), Carnuntum experienced an economic boom, the reaching their maximum size.
Caracalla elevated it to status as . He was killed shortly afterwards by his own soldiers, probably at Carnuntum.

Civilian city

The remains of the civilian city extend around the village
Petronell-Carnuntum. There are several places to see in the city: Roman city quarter in the open-air museum, palace ruins,
amphitheatre, and Heidentor.
The Roman city ruins are exposed in the open-air museum directly in the present village. One of the ancient houses, called the House of Lucius, has been rebuilt using traditional techniques. It was opened to the public on 1 June 2006.
The was next to the palace ruins, also referred to as the large
public baths.
Some way outside the city was a large amphitheatre, which had room for about 15,000 spectators.
A plate with an inscription found at the site claims that this building was the fourth largest amphitheatre in the whole Roman Empire.
Heidentor
Between 354 AD and 361 AD, a huge triumphal monument was erected next to the camp and city. Contemporary reports suggest that Emperor
Constantius II had it built to commemorate his victories. When the remains of Carnuntum disappeared after the Migration Period the monument remained as an isolated building in a natural landscape and led Medieval people to believe it was the tomb of a pagan giant. Hence, they called it ('Heathens' Gate' or 'Pagans' Gate').
Fortress

The only remaining building of the fortress is an amphitheatre, located just outside the fortress. Today, a small adjacent museum shows the history of

Gladiator school
In September 2011 aerial photographs and ground-penetrating radar led to the discovery of the typical contours of an ancient Roman gladiator school to the south of the Roman settlement, a rivaling the
Ludus Magnus school and covering an area of some . This approach of aerial photography and modern remote sensing has allowed for a detailed virtual recreation of the gladiator school. The aerial photographs used in the recreation were acquired with a radio-controlled Microdrone md4-1000 quadrocopter, which captured a sufficient number of photographs to create an overlap among them. Then, using a technique called ''
structure from motion (SfM)'', a 3D model of the school was calculated using the sharpest images.
The school, along with the amphitheater, was located outside of the town's walls. The school had training grounds, bathing facilities, an assembly hall and dormitories for the gladiators. The school also had a courtyard which housed a training area for gladiators. The school was attached to an open campus which was most likely used for chariot races.
