Les Ferreres Aqueduct (also known as Pont del Diable meaning Devil’s Bridge) was built to take water from the Francoli water 15 kilometers (9 miles) south to the city of Tarragona.

The Baths of Caracalla were Roman public baths, or thermae, built in Rome between AD 212 and 216, during the reign of the Emperor Caracalla. The complex of buildings was more a leisure centre than just a series of baths. Besides being able to hold an estimated 1,600 bathers, it also featured a public library and a wrestling school. The baths remained in use until the 6th century when the complex was sacked by the Ostrogoths during the Gothic War, destroying the hydraulic installations.

The Valens Aqueduct was completed in the year 368 AD during the reign of Roman Emperor Valens, whose name it bears. It was merely one of the terminal points of a system of ancient aqueducts and canals – which eventually reached over 250 kilometers (155 miles) in total length, the longest such system of Antiquity. The Valens Aqueduct was restored by several Ottoman Sultans and was still the major water-providing system of medieval Constantinople.

The Roman Theater of Amman was built during the reign of Marcus Aurelius in the 2nd century AD. It is cut into the hillside and oriented north to keep the sun off the spectators. The theater was built on three tiers: the rulers, sat closest to the action, the military had the middle section, and the general public sat on the highest section. Although far from the stage, even there the actors could be clearly heard, owing to the steepness of the theater.

Lucius Septimius Severus was a Roman Emperor born in Leptis Magna who reigned 193 until his death in 211. The citizens of Leptis probably started the construction immediately after their fellow citizen had become emperor. The central scene on the arch shows the emperor shaking hands with his sons, Caracalla and Geta. Caracalla is shown as a tall young man and this offers a clue for the moment of completion of the arch, probably in the early 200’s.

Arch of Titus in Rome was constructed in 82 AD by the Roman Emperor Domitian shortly after the death of his older brother Titus to commemorate Titus’ victory in the Sack of Jerusalem in 70 AD.

The Roman Baths are a must-see tourist attraction in the English city of Bath. A temple was constructed in 60-70 AD and the bathing complex, which are fueled by England’s only mineral hot springs, was gradually built up over the next 300 years. The water that flows through the Roman Baths is considered unsafe for bathing, partly because it passes through the still-functioning original lead pipes and because of the significant danger of infectious diseases. In 1979 a girl swimming in the restored bath swallowed some of the source water, and died five days later from amoebic meningitis.

The Rotunda has a diameter of 24.5 meters (80 feet). Its walls are more than 6 meters (20 feet) thick, which is one reason why it has withstood Thessaloniki’s earthquakes. A flat brick dome, 30 meters (98 feet) high at the peak, crowns the cylindrical structure.
