in their urban plans. Each city proposed its own particular planning solutions, but with regard to the choice of public buildings and their style of decoration, there was a surprising similarity among them. The city of Gadara was endowed with all these edifices, characteristic for the roman plan. Mentionned are : The Domestic Quarters (Residential Area), the West Theater, Cardo Maximus with shops, Nymphaeum, the Podium Monument, Roman and Byzantine Baths, the North Theater, Hellenistic Temple, Eastern City Gate, Tombs and Mausoleums, Sanctuaries.The city of Gerasa and the city of Abila were also important sites with similarities in urban planning. The study mentions the architecture of baths (Wadi Arabah and Gerasa) The Nymphaeums that were a grand public fountain (Petra and Gerasa) The Theaters and Odeons ( Two in Gerasa, the Philadelphia theater in Amman, The Three Theaters in Cadara, the Theater in Petra, and the Theater in Abila) The Temples that testify the Greek influence, like this in Gerasa, dedicated to Artemis, daughter of Zeus and sister of Apollo that was the patron goddess of the city and that of Zeus, in the same city. The most famous – may be – of the advanced engineering works of the romans were the aqueducts, a technology known all over the empire. In Jordan there are in Gerasa, the Ancient World's Longest Underground Aqueduct in Gadara: Others, not of less importance are found in the Humeima/Auara, in Negev, in Amman, in Abila, in Wadi Arabah. Vault bridges are built of limestone and local basalt, as described in the study. Species of the kind are found in Wadi Quelbeh, in Abila, in Gerasa and above the Jordan River. The King’s Highway runs through the important cities of Heshbon, Medeba, Dibon, Kerak, Bozrah and Petra. In the early 2nd century AD, Trajan used this route to build his "Via Nova Trajana”. The romans wanted to connect the provinces between them with large roads, which facilitated the commerce, the communication and the transport of the army.
One of the primary routes of
commerce, which was defined later as “The Incense Route”, started in the southern part of the Arabian Peninsula, where some of the finer perfume plants were grown, continued to the north and arrived after 65 stations and few divisions, to Petra. As for the traces of the roman technology in contemporary practices it is to mention the inventions like the roman concrete, the construction of arches, engines for watering and movement (steam engines, cattle mills and watermills), inventions in glass, pottery and metallurgy etc. The study continues in the domain of intangible heritage, that is the linguistic traces, words and expressions that come from greek or latin. Names of cities, of course, such as Petra, first names of
