Archaeological remains , found below Hoher Markt Remains of the Roman military camp have been found at many sites in the centre of Vienna. The centre of the Michaelerplatz has been widely investigated by archaeologists. Here, traces of a Roman legionary outpost (
canabae legionis) and of a crossroad have been found. The centrepiece of the current design of the square is a
rectangular opening that evokes the archaeological excavations at the site and shows wall remains that have been preserved from different epochs. Part of a Roman canal system is underneath the fire station am Hof. Directly under the Hoher Markt are the remains of two buildings unearthed during the canalisation works of 1948/49 and made accessible to the public. After further excavation, a showroom was opened in 1961. For this purpose some of the original walls had to be removed; white marks on the floor show the spots where. The buildings, which are separated from one another by a road, housed an officer and his family. In 2008 this Roman ruins exhibit was expanded into the
Museum of the Romans. Only a small portion can today be seen, for the majority of the remains are still located underneath the square and south of it. The remains of the walls date from different phases from the 1st to the 5th century AD. The houses were typical Roman villas, with living quarters and space for working set around a middle courtyard with columned halls. During drillings for the U5 underground line, new brick kiln and metal smelting sites were discovered that revealed further reaching suburbs of the ancient Roman settlement.
Evidence for the Roman military presence Over 3,000 stamped bricks, several stone monuments and written sources prove that several legions, cavalry units and marines were stationed in Vindobona. Around 97 AD,
Legio XIII Gemina was responsible for construction of the legionary camps. Because of the wars in Dacia, they were pulled out and redeployed in 101 AD. A decade later, Legio XIIII Gemina Martia Victrix followed.
Legio X Gemina from Aquincum arrived in 114 AD and remained in Vindobona until the 5th century. About 6,000 soldiers were stationed in the Roman camp. Many of them were free from active duty during peaceful times and had other jobs. These so-called
immunes were needed for the supply of goods and for the production and maintenance of weapons and commodities. They also extracted stone from quarries and wood from forests, produced bricks, and maintained the streets, bridges and the water system. Administrating the camp and ensuring its security required additional manpower.
Roman canals The
Romans provided their cities, including Vindobona, with clean
potable water through an elaborate systems of
Roman aqueducts,
canals, and large
subterranean pipes. Excavations have revealed that Vindobona received its supply through a 17 km long water pipeline. The source is in the
Vienna Woods around today's
Kalksburg. Wells,
latrines and the
thermae were supplied with water. Central buildings such as the commander's office and the hospital had their own supplies, as did the settlement outside the camp, where households had their own
groundwater wells.
Archaeological excavations done over the last 100 years have discovered the following Roman
water supply fragment locations: • In the Zemlinskygasse:
at numbers 2-4 - (23rd district, found in 1924) • In the Breitenfurter Straße:
at number 422 - (23rd district, in 1959) • In the Rudolf Zeller-Gasse/Anton-Krieger-Gasse - (23rd district, 1992) • In Atzgersdorf - (23rd district, 1902–1907) • In the Tullnertalgasse:
at number 76 - (23rd district, 1973) • In the Lainergasse:
at number 1 - (23rd district, 1958) • In the Wundtgasse - (12th district, 1951) • In the Rosenhügelstraße:
at number 88 - (12th district, 1926) • In the Fasangartenstraße:
at number 49 - (12th district, 1916) • In the Pacassistraße - (13th district, 1928) • In the Sechshauserstraße:
at number 7 - (15th district, 1879 -
leading towards the first district) Waste from the Roman camp was transported through an elaborate subterranean
sewerage system that was planned from the beginning. The sewers were lined with
brick walls and plates and ran beneath the main roads.
Gradients were used in such a way that the waste water descended through the canals into the
River Danube. Since the canals were up to two meters deep, they could be cleaned out regularly. Large waste was probably deposed at the slope of the river. In the civilian settlement, waste was deposed in former
water wells and dumps.
Legacies in today's streets The layout of a Roman camp (
castra) was normally standardised. This has helped archaeologists to reconstruct what the camp must have looked like, despite the heavy rebuilding that has taken place in Vienna throughout the centuries. The basic contours of the camp, which was surrounded by a mighty wall with towers and three moats (today the Tiefer Graben, Naglergasse, Graben, and Rotenturmstraße) are identifiable. Along these axes, main roads connected the gates with one other. The main buildings were the commander's headquarters, the Palace of the Legate, the houses of the staff officers, and the thermae. At right angles to these, the soldiers' accommodation, a hospital, workshops, and mews (stables) were constructed. ==In popular culture==
