 Visual inspection in Slottsfjellet museum, Tønsberg, Norway

In the framework of the Hyperion project, the research groups from the Oslo Metropolitan University visited Slottsfjellet museum in Tønsberg, Norway.

During their visit, they conducted a visual inspection of the buildings (the Fadum storehouse and the Heierstadt Loft, both Tier 1 buildings) in the pilot-area in order to identify their deterioration factors. They also installed sensors to monitor the hygrothermal performance of the two historic constructions.

 2nd Plenary Meeting of Hyperion EU project 

The 2nd Plenary meeting took place virtually, from 22-23 April 2020, as Granada, city of Spain, was one of the cities also suffering from the results of the pandemic. The persons in charge of the work packages presented the progress of their work specifying the difficulties they faced and set the goals for the next semester. The two-day meeting ended successfully and Athens was appointed to host the next meeting in October 2020, if the current situation permits it.

 Hyperion Demos in the city of Granada (Spain)

In Granada, there are around 2,000 monumental buildings with various preservation-related problems. Near Granada, we can see what could be one of the first domes in the history of construction, Tholos de El Romeral, built around 3000 BC. Several tribes and cultures have been around in the area. Granada county has the first diocese (seat of the bishop) in Spain. Granada has been Islamic during the period 711-1492 AD. In Granada city, few constructions before the Islamic occupation period remain, although several constructions from the time of the Islamic period are still standing, especially in the Albayzín.

 Survey at the Clock Tower, Venice

The first week of June University of Padova, IUAV University of Venice, and the CVI, partners of the H2020, Hyperion project visited  St Mark's Clocktower,  in Venice, to conduct a survey.

The aim of the visit was to study where the smart tags might be positioned. The group examined all possible locations, for placing the measuring kit, considering all the factors that may interact with the measuring instruments (e.g. shadow for the neighboring buildings). Also, the measuring kit should be practically invisible, so as not to alter the external view of the monument.   

The onsite visit was very helpful for the continuation of the project as the Cultural Heritage building is located in the Center of Venice (San Marco Square).

 Geometric imprint of the registered monuments in Rhodes, Greece

From the 15th to the 24th of June 2020, the research group from the Laboratory of Photogrammetry of the National Technical University of Athens arrived in Rhodes, under Professor Andreas Georgopoulos, to create a three-dimensional geometric imprint of the monuments which are registered for the Ηyperion project. The 5th Ephorate of antiquities of the Dodecanese participated in this action.

The two medieval monuments, proposed by the Municipality of Rhodes, the fortress of Agios Nikolaos and the Tower of Naillac, as well as the monuments proposed by EFAD, the Roman bridge, and the two Hellenistic burial complexes at the Archaeological Site of Rodini, were imprinted.

The Archaeological Site of Rodini (Partial View)
EFAD’s surveyor Fanourios Roditis imprinted the fortress of Agios Nikolaos with the terrestrial laser scanner system provided by the Ephorate. The imprints, in addition to being necessary for the implementation of the goals of the program, were also valuable for the archaeological documentation of some of the monuments, as for the Roman bridge there was no geometric imprint until now, while the burial precincts in the archeological site of Rodini have never been imprinted before.

In order to prepare the imprint, EFAD  carried out all the required bureaucratic procedures, such as approval for the flight of the drone, information on the flight, issuance of a decision of cessation of traffic over the  Roman bridge from Rhodes Traffic control, etc.
Roman Bridge: Cessation of traffic during the measurements
For imprinting the monuments, it was also necessary to clean up the area from the vegetation, which was also undertaken entirely by EFAD. The fortress of Agios Nikolaos, the tower of Naillac, and the burial complexes in Rodini were cleaned up by employees of the Ephorate. Also, the crane vehicle of the Ephorate was used to clean the upper parts of the walls in the fortress of Agios Nikolaos.
Initial status with the natural vegetation
Large-scale clean-ups were also carried out on the Roman bridge, inside the bed of the Rodini torrent, where the vegetation was dense and had hidden the sides of the bridge. The cleaning, done by the contracting company, lasted about 12 days. A digging machine was used in the area west of the bridge, where there was access to wheeled vehicles. On the east side of the bridge, where it was impossible for a vehicle to approach, the grass as well as a lot of garbage, were removed manually, and they were transported out of the riverbed, by the appointed contractor. The Municipality of Rhodes also assisted in the collection of the waste material. The monument was then ready, for the predefined measurements, made by the appointed staff of the National Technical University.
