Timgad, also known as Marciana Traiana Thamugadi, was a Roman city in the Aurès Mountains of Algeria. It was built by Emperor Trajan around 100 AD. The city's full name was Colonia Marciana Ulpia Traiana Thamugadi. Emperor Trajan named the city to honor his mother, Marcia, his sister, Ulpia Marciana, and his father, Marcus Ulpius Traianus.

Timgad is located in modern-day Algeria, about 35 kilometers (22 miles) east of the city of Batna. The ruins are important because they show one of the best examples of a Roman grid plan used for city design. In 1982, UNESCO added Timgad to the list of World Heritage Sites.

Name

The city now known as Timgad was originally called Marciana Traiana Thamugadi. The first part of the name, Marciana Traiana, comes from the Roman Empire and is named after Emperor Trajan and his sister Marciana. The second part, Thamugadi, is not Latin. It is the Berber name for the area where the city was built. Thamugadi is the plural form of the Berber word Tamgut, which means "peak" or "summit."

History

The city was established as a Colonia by Emperor Trajan in the year 100 AD. It was built mainly as a Roman stronghold to protect against the Berbers living near the Aures Mountains. The city was originally settled by Roman soldiers and colonists who had never visited Rome before, despite being hundreds of miles away from the Italian city. These people focused heavily on Roman traditions and identity.

For the first few hundred years, the city remained peaceful and became an important center for Christian activity starting in the 3rd century. It became a key location for the Donatist movement in the 4th century. During this time, Timgad was a diocese, and it gained fame when Bishop Optat became a leader of the Donatist movement by the end of the 4th century. After Optat, the city had two bishops: Gaudentius, who was a Donatist, and Faustinus, who was Catholic.

In the 5th century, the city was attacked and destroyed by the Vandals before beginning to decline. Later, Berber tribes from the Aures Mountains destroyed Timgad completely at the end of the 5th century. In 539 AD, during the Moorish wars, the Byzantine general Solomon captured and rebuilt the city, adding it to Byzantine North Africa. This rebuilding helped restart some activities in the city, which became part of a defensive line against the Moors. However, early Muslim conquests led to the city’s final decline, and it was no longer inhabited by the 8th century.

In 1765, Scottish explorer James Bruce visited the ruins of the city on December 12, likely being the first European to see the site in many years. He described it as “a small town, but full of elegant buildings.” In 1790, Bruce published a book called Travels to Discover the Source of the Nile, where he wrote about his findings in Timgad. Many people in Great Britain doubted his account until 1875, when Robert Lambert Playfair, a British official in Algeria, visited the site based on Bruce’s description. In 1877, Playfair wrote a book titled Travels in the Footsteps of Bruce in Algeria and Tunis, where he described the ruins in more detail. He noted, “These hills are covered with countless numbers of the most interesting mega-lithic remains.” French colonists took control of the site in 1881 and began studying and preserving it until 1960. During this time, the site was carefully explored and excavated.

In the 1880s, the Ministry of Public Education and Fine Arts started excavations in Timgad. A position called “chief architect of historical monuments of Algeria” was created to oversee the protection, excavation, and restoration of historical sites in the region.

Description

The city is located where six roads meet. It had walls but was not strongly protected. Originally planned for about 15,000 people, the city grew quickly and expanded beyond its original grid pattern in a less organized way.

When the city was founded, the surrounding area was fertile farmland, about 1,000 meters above sea level. The original Roman design, with straight streets forming a grid, is still visible today. The main east-west street, called the decumanus maximus, and the main north-south street, called the cardo, are lined with partially restored columns in the Corinthian style. The cardo ends at a central square where it crosses the decumanus.

At the western end of the decumanus stands a 12-meter-high triumphal arch known as the Arch of Trajan. It was partially restored in 1900 and is mainly made of sandstone. The arch has three openings, with the middle one measuring 11 feet wide. It is also called the Timgad Arch.

A well-preserved theater with 3,500 seats is still used for performances today. Other important buildings include four public baths, a library, and a basilica. The Capitoline Temple, dedicated to Jupiter, is about the same size as the Pantheon in Rome. Near the temple is a square church with a circular apse built in the 7th century AD. One of the city’s religious sites featured images of (Dea) Africa. South of the city lies a large Byzantine citadel constructed during the city’s later years.

Library

The Library at Timgad was a gift to the Roman people by Julius Quintianus Flavius Rogatianus. It cost 400,000 sesterces. No additional information about this person has been found, so the exact date the library was built is unknown. Scholars believe, based on archaeological evidence, that it was built in the late 3rd or 4th century.

The library was rectangular in shape, measuring 81 feet (25 meters) long and 77 feet (23 meters) wide. It included a large semi-circular room next to two smaller rectangular rooms. A U-shaped colonnaded portico surrounded three sides of an open courtyard. The portico was flanked by two long, narrow rooms on each side. The large vaulted hall likely served as a reading room, storage area, and possibly a lecture room. Long, narrow alcoves contained wooden shelves along the walls. These shelves likely had sides, backs, and doors, as similar evidence was found at the library in Ephesus.

There may have been free-standing bookcases in the center of the room, as well as a reading desk. While the library’s architecture is not especially unique, its discovery shows that Timgad had a fully developed library system. This indicates a high level of learning and culture in the city. Although no records of the library’s collection size exist, experts estimate it could have held about 3,000 scrolls.
