DanubeThe Danube (ˈdæn.juːb ; ) is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Southeastern Europe, from the Black Forest into the Black Sea. A large and historically important river, it was once a frontier of the Roman Empire and today connects ten European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine.
Đerdap National ParkĐerdap National Park (Национални парк Ђердап / Nacionalni park Đerdap) stretches along the right bank of the Danube River from the Golubac Fortress (Голубачки град / Golubački grad) to the dam near Novi Sip, Serbia. It was established in 1974 and spreads on . The park management office is in the town of Donji Milanovac on the Danube. Across the river is the Parcul Natural Porțile de Fier in Romania. In July 2020 the wider area of the national park was designated as the UNESCO global geopark, as the first protected area from Serbia labeled that way.
Ancient Roman engineeringThe ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, but transformed by the Romans into a technology inconceivable in Greece. The architecture used in Rome was strongly influenced by Greek and Etruscan sources. Roman roads Roads were common at that time, but the Romans improved their design and perfected the construction to the extent that many of their roads are still in use today.
Roman armyThe Roman army (Latin: exercitus Romanus) was the armed forces deployed by the Romans throughout the duration of Ancient Rome, from the Roman Kingdom (753 BC–509 BC) to the Roman Republic (509 BC–27 BC) and the Roman Empire (27 BC–476 AD), and its medieval continuation, the Eastern Roman Empire. It is thus a term that may span approximately 2,205 years (753 BC–1453 AD), during which the Roman armed forces underwent numerous permutations in size, composition, organisation, equipment and tactics, while conserving a core of lasting traditions.
Trajan's ColumnTrajan's Column (Colonna Traiana, Columna Traiani) is a Roman triumphal column in Rome, Italy, that commemorates Roman emperor Trajan's victory in the Dacian Wars. It was probably constructed under the supervision of the architect Apollodorus of Damascus at the order of the Roman Senate. It is located in Trajan's Forum, north of the Roman Forum. Completed in AD 113, the freestanding column is most famous for its spiral bas relief, which depicts the wars between the Romans and Dacians (101–102 and 105–106).
BridgeA bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations.
MoesiaMoesia (ˈmiːʃə,-siə,-ʒə; Latin: Moesia; Moisía) was an ancient region and later Roman province situated in the Balkans south of the Danube River, which included most of the territory of modern eastern Serbia, Kosovo, north-eastern Albania, northern parts of North Macedonia (Moesia Superior), Northern Bulgaria, Romanian Dobruja and small parts of Southern Ukraine (Moesia Inferior). In ancient geographical sources, Moesia was bounded to the south by the Haemus (Balkan Mountains) and Scardus (Šar) mountains, to the west by the Drinus (Drina) river, on the north by the Donaris (Danube) and on the east by the Euxine (Black Sea).
BanatBanat (UKˈbænɪt,_ˈbɑːn-, USbəˈnɑːt,_bɑːn-; Bánság; Banat) is a geographical and historical region that straddles Central and Eastern Europe and which is currently divided among three countries: the eastern part lies in western Romania (the counties of Timiș, Caraș-Severin, Arad south of the Mureș river, and the western part of Mehedinți); the western part of Banat is in northeastern Serbia (mostly included in Vojvodina, except for a small part included in the Belgrade Region); and a small northern part lies
ArchAn arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures.
Ancient RomeIn modern historiography, ancient Rome refers to Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC), and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula.
