The German Archaeological Institute has been involved in refurbishing the National Museum of Cherchell (Algeria) since 2008 using funding from the Cultural Preservation Programme of the Federal Foreign Office. Around two millennia ago, the ancient port of Caesarea Mauretaniae was the seat of the kings of Mauritania for 65 years. The National Museum of Cherchell houses finds of the highest quality from the city’s unparalleled heyday and from the following centuries under Roman rule.
The famous palace complex of the Roman Emperor Nero is being restored by the Parco archeologico del Colosseo (MIBACT) since 2009. The project is supported by the German Archaeological Institute in Rome.
To understand the story of Domus Aurea, the “Golden House”, one must go back to a summer’s night between the 18th and 19th of July in the year 64 AD. That night, as Tacitus (c. 56 – c. 120 AD), senator and a historian of the Roman Empire, tells us in his annals, a fire broke out in ancient Rome. Raging for nine days the fire reduced nine of the thirteen districts of Rome to ashes and rubble. According to the rumors that spread quickly in Rome, the fire is said to have been laid on the orders of Emperor Nero, to be able to sing from a tower of the downfall of Troy. The persistence of such rumors may be explained by the fact that part of the city was used for the construction of Nero’s new palace complex, Domus Aurea.
The palace complex of Domus Aurea
Domus Aurea probably is the most impressive example of Neronian architecture. According to ancient historians, Suetonius and Tacitus, the wide spread complex, included an artificial lake, vineyards, cornfields, pastures and forests, populated with wild game and grazing livestock. We are informed that the buildings “seemed like cities” and offered an imposing view with a 120 feet high statue of Nero standing in the vestibule.
Most of what has survived belonged to the part of the Domus Aurea, which is located on the side of the Oppian Hill. It is believed, that these 142 rooms belonged to the main building of the complex. The exact dimensions of the building complex are not known, yet. The entire complex, which was not finished at the time of Nero’s death in 68 AD, was rebuilt during the reign of following emperors. After a fire broke out in the residence building in 104 AD the upper floor was levelled and the basement buried under the Baths of Trajan (106-109 AD).
Restoration work at Domus Aurea
During the time of Emperor Trajan the basement was filled up and all windows were sealed, to use the area as the base of Trajan’s Baths. Of the chambers added to widen the base, two collapsed in 2010, making immediate restoration measures necessary.
The reason for the collapse was a lack of structural safety, caused by the public park above Domus Aurea and looting. The ruins were used as a source for building material since the Middle Ages. What remained was only the inner part of the wall, the so-called nucleo, which consists of low-quality mortar and bricks. Due to the moisture this exposed nucleo was damaged over the centuries.
The first challenge for was to set up and implement a restoration concept that took into account all aspects of the building. In addition to the restoration of the static safety of the building, measures to prevent the ingress of rainwater were implemented. To stop excessive air circulation, which can result in the transport of dust particles and salt efflorescence in the masonry, air locks were installed. Furthermore, the algae infestation had to be reduced and roots, damaging the structure, were diminished. The park area covering Domus Aurea was redesigned in accordance to the restoration concept.
Since November 2014, Domus Aurea is open to guide tours again on the weekend, thanks to the work of Parco archeologico del Colosseo (MIBACT). The measures were funded by the Italian State and the German Archaeological Institute.
Works of art and edifices testify to Viet Nam’s culture reaching back for centuries. They convey past lifestyles to today’s generations in an impressive way – to the Vietnamese population and to tourists from around the world alike. But works of art have a tough time in Viet Nam. The humid and warm climate, past military conflicts and maintenance work neglected and postponed over many decades have taken their toll on these unique buildings.
Conservation and restoration in line with UNESCO standards
The conservation and restoration of the portal, screen and basin of the Phung Tien Temple began in August 2017 with an accompanying training programme. The almost 200 year old construction is one of the most valuable examples of original preserved architecture from the early period of construction of the imperial city designed in accordance with Feng Shui rules. In contrast to the temple on the site, which was destroyed in 1947, it has withstood the test of time. Traditional building materials and technologies as well as modern conservation materials and methods are being drawn on. A special emphasis is placed on the development and application of an authentic restoration method for frescos and buildings featuring coloured plastering. The project with an accompanying training programme is being implemented with employees from local restoration companies and the Hué Monuments Conservation Centre, as well as freelance artisans.
