The Mainzer Zitadelle (Citadel of Mainz) was constructed in 1660. The Jakobsberg hill, where the citadel was constructed, had been occupied by a Benedictine abbey during the middle ages (since 1050). Halfway up the hill, the amphitheater of the Roman settlement of Mogontiacum, which has been recently excavated, must also have been visible at that time. The Jakobsberg hill, however, had not been integrated in the ring of the defensive city walls of the town and this flank of the city was therefore only slightly protected. This position immediately at the gates of the town opened a strategic gap, as an aggressor could use the hill for a raid into Mainz or for a cannonade. The construction of the 'Schweickhardtsburg' fortress under the supervision of cathedral vicar Adolph von Waldenburg during the years 1620-29 provisionally filled this gap and integrated the hill into the system of city walls. The name of the irregularly pentagonal fortification honors the reigning monarch of that time, the prince-elector Johann Schweikhard von Kronberg.
Around 1655 prince-elector Johann Philipp von Schönborn initiated an improvement of the fortification of the entire town comprising bastions according to French type. Within this modification of the fortress, the Schweickhardtsburg was converted into the regular, quadrangular citadel, as it is today. St. Jacobs abbey and the Roman cenotaph, the Drususstein, remained untouched within the fortress.
Above the gate in direction to the town, a building for the commander of the citadel was erected in 1696 by the order of Lothar Franz von Schönborn. The gateway, existing since 1660 was skillfully integrated in the new building.
During the siege of Mainz (1793) St. Jacobs abbey was destroyed largely by Prussian shelling. The remainings of the abbots and guest house had been used only for military purposes since then. In the south of the courtyard a baroque garden existed, which can be seen on a map dated 1804.
After the Napoleonic Wars Mainz became in 1816 a fortress of the German Confederation. Prussians and Austrians settled in the citadel and used it as barracks. For this purpose, the Austrians erected 1861 the shellproof Citadel Barracks; the small side building was used as casino and kitchen.
Even in 1914 a double company barracks was erected. Due to this, the last remainings of the abbey declined. However numerous architectural elements of the abbot and guest houses had been integrated in the new buildings. During World War I and World War II the citadel was used as prisoner-of-war camp (Oflag XII-B).
According to the Treaty of Versailles in 1919 - and the slighting of the fortifications in and around Mainz as effect of it- the military history of the citadel of Mainz ended. Nevertheless, during the last days of WWII, the population of Mainz took shelter in the casemates of bastion Drusus, which had been turned into air raid shelters.
After the Second World War the French army seized the premises until 1955. The Paul Tirard School, named after the chair of the Inter-Allied Rhineland High Commission (1919–1930), was opened by the French administration in 1950 for education of the children of French military and civilian personnel civil during the occupation.
Today the citadel is owned by the city of Mainz and accommodates numerous municipal offices. The Mainz Citadel belongs officially to the cultural heritage since 1907. The trench in the southern part of the citadel had been considered natural heritage since the 1980s. One of the buildings near the Drususstein accommodates the Historical Museum of the Town Mainz today.
The citadel and its surroundings bear witness to the entire history of Mainz concentrated in one spot: commencing with the Roman cenotaph Drususstein via the barracks of the federal fortress up to the air raid shelters of World War II.References:
Kerameikos was the potters" quarter of the city, from which the English word 'ceramic' is derived, and was also the site of an important cemetery and numerous funerary sculptures erected along the road out of the city towards Eleusis.
The earliest tombs at the Kerameikos date from the Early Bronze Age (2700-2000 BC), and the cemetery appears to have continuously expanded from the sub-Mycenaean period (1100-1000 BC). In the Geometric (1000-700 BC) and Archaic periods (700-480 BC) the number of tombs increased; they were arranged inside tumuli or marked by funerary monuments. The cemetery was used incessantly from the Hellenistic period until the Early Christian period (338 BC until approximately the sixth century AD).
The most important Athenian vases come from the tombs of the Kerameikos. Among them is the famous “Dipylon Oinochoe”, which bears the earliest inscription written in the Greek alphabet (second half of the eighth century BC). The site"s small museum houses the finds from the Kerameikos excavations.
