Founded during the eighth-century Umayyad caliphate, the city of Anjar was an inland trading centre at the crossroads of two important routes: one connecting the Mediterranean coast with the Syrian interior, and the other linking northern Syria with northern Palestine. Archaeologists only discovered the site at the end of the 1940s when excavations uncovered a fortified city covering an area of some 114,000 square metres and surrounded by two-metre-thick walls.
Two main 20-metre-wide streets, a north-south axis (cardo maximus) and an east-west axis (decumanus maximus), divide the city into four equal quarters, with private and public buildings laid out according to a strict plan: the partially rebuilt Grand Palace with its central courtyard surrounded by a peristyle, the Small Palace with its numerous ornamental fragments and its richly decorated central entrance, and a mosque located between the two palaces, as well as small harems and baths. The ruins are dominated by a monumental Tetrapylon, a structure consisting of four columns which stands at the crossroads of the two main streets. These structures incorporate decorative or architectural elements of the Roman era.
Anjar is one of five cultural UNESCO World Heritage Sites in Lebanon.
Baalbek is an ancient Phoenician city located in what is now modern-day Lebanon, in the northern part of the Beqaa Valley, a fertile area with plentiful springs. First settled at the beginning of the 3rd millennium BC, Baalbek was an essential waypoint on the Phoenician trade route from Tyre to Damascus and grew into an important pilgrimage where the god Baal, the sun god, was worshipped alongside his consort Astarte, the Queen of Heaven. The city, renamed Heliopolis (City of the Sun) by the Greeks, is now famous for its exceptionally well-preserved colossal sanctuary built during the Roman period and for its three main gods: Jupiter Heliopolitanus, Venus Heliopolitana, and Mercury Heliopolitanus. Baalbek is one of the most remarkably preserved complexes in the Middle East and Lebanon’s most celebrated archaeological attraction. It was inscribed as a UNESCO World Heritage site in 1984.
The history of settlement at Baalbek can be traced back to the Chalcolithic and Early Bronze Age. This first settlement had been on the hilltop of Tell Baalbek, and it is likely that this place was the focus of some worship. During the Canaanite period, the local temples were largely devoted to the Heliopolitan Triad: Baʿal, his consort Ashtart, and their son Adon. The name Baalbek, probably Canaanite for “Lord of the spring” in reference to the god Baal, may reflect the nature of the original cult. However, it appears only in the 5th century AD.
Baalbek was transformed into a fortification during the Hellenistic period when the Seleucid Empire struggled for regional power against the Ptolemies of Egypt (198 BC). It was probably during this time that the town was renamed Heliopolis, the City of the Sun. This name was retained following the onset of Roman rule in 64 BC when Pompey conquered Syria and Palestine. Heliopolis became part of the first Roman colony in Syria, which was created in Berytus (Beirut), but under Septimius Severus, the city gained its independence and was renamed Colonia Julia Augusta Felix Heliopolitana.
The main construction campaign in the sanctuary complex lasted over 200 years, from the mid-1st century AD to the 3rd century AD. It began with the construction of a T-shaped terrace approximately 12 m high, a propylon and a small altar in the central courtyard. The colossal temple dedicated to Jupiter Heliopolitanus, a powerful god of agricultural fertility and the cosmos, was built in the 1st century AD during the second phase of construction. Constructed on a podium 7m above the surrounding courtyard, the temple followed a peripteral Greek design of 10 by 19 columns in the Corinthian order. However, only six of the original 54 columns remain, but they give no doubt as to the grandeur of this enormous structure. Covering an area of approximately 48 by 88 m, it was one of the largest temples dated to the Roman period.
The third phase of construction at the sanctuary was undertaken initially by Hadrian and continued through the Antonine period. During this phase, the courtyard was expanded and embellished with 128 red granite columns from Aswan in Egypt as well as additional rooms and semicircular exedrae. The Great Altar, built five meters to the east of the Small Altar, was about 14 m high and had a staircase leading to a sacrificial platform. The grandiose structures of the third phase remained unfinished.
The final phase of construction at the sanctuary in the early 3rd century AD under the emperor Septimius Severus reflects changes in the city’s political status and religious activities. The visit of Caracalla and his mother, Julia Domna, in AD 215, resulted in the construction of the Hexagonal Courtyard and the Propylaeum which included three columns capitals in gilded bronze honouring them and inscriptions on column bases mentioning Caracalla. The so-called Temple of Bacchus was also added during this period. It was attributed to the god of wine Bacchus on the basis of Dionysiac motifs decorating the temple. However, the temple may have been used for the imperial cult in addition to other gods such as Bacchus and possibly Venus. The last building constructed at the complex is a small round temple built on a tall podium.
Quarries located approximately 1 km to the south and west provided local limestone for the sanctuary’s construction, and granite was imported from both Egypt and the Troad in northwestern Anatolia for hundreds of massive columns.
The Temple of Jupiter also served as an oracle. The 5th-century Roman author Macrobius recorded that Trajan, before embarking on his second Parthian campaign, consulted the oracle at Heliopolis who predicted his imminent death. Although it is not known if Hadrian ever visited Heliopolis, he spent considerable time in the region and contributed greatly to the completion and embellishment of the Temple.
The rise of Christianity changed the fortunes of Heliopolis-Baalbek. Much of the sanctuary was destroyed at the end of the 4th century by the emperor Theodosius I who constructed a church in the courtyard of the Temple of Jupiter. The round temple was also converted into a church. Baalbek was later incorporated in the Islamic Empire in AD 635, and in the 12th-14th centuries AD, the preserved temple areas were incorporated into a large fortress.
Scientific work on the ruins began as early as the 17th century, with detailed reproductions of the above-ground structures. However, systematic excavations were only launched in 1898 thanks to the journey of the German Emperor William II. Deeply impressed by the beauty and size of the monuments, he requested their proper investigation and documentation. Through the course of the 20th century, German and French scholars and archaeologists along with Lebanese professionals uncovered and recorded the main parts of the ruins. After the end of the civil war in 1991 archaeological investigations could again be envisioned; in 1997 a co-operation program was inaugurated between the DGA and the Deutsches Archäologisches Institut (DAI).
