In Greece as well, OSMOS takes care of the world heritage. Our subsidiary OSMOS Hellas is now monitoring a part of the Acropolis of Athens with our technologies, one of the World Heritage listed monument (by UNESCO).
A place filled with history
The “Propylaia”, the monumental entrance gate of the Acropolis in Athens, was built between 437 and 432 B.C. by the architect Mnesiclès as part of the works of Périclès. Made of white Pentelic marble and gray Eleusinian marble or limestone, the Propylaia of the Acropolis, is one of the world’s most famous monuments and combines doric facade with ionic columns. The ancient structure is divided into one main central room and two lateral wings, one of them leading to the Athena temple.
Light instrumentation, confirmed bearing capacity Because of the oldness of the building, the client is concerned that earth pressures might cause damages to the structure. In order to identify the actual risks, OSMOS Hellas installed four Optical Strands, one monitoring station and one temperature sensor on the Propylaia walls. The OSMOS installation provides the client with information about the impact of earth pressures or
any other events, like earthquakes, on the structure.
The static and dynamic deformations first results showed that the instrumented wall’s structural behaviour is stable. OSMOS was therefore able to confirm the bearing capacity of the wall and the foundation system.
Preserving the cultural heritage
Nowadays, after various restoration works since 1984, the Propylaia is used as the entrance to the Acropolis by thousands of tourists every year. Hence, the Propylaia is an important cultural heritage for Greece and a
famous tourist attraction. Thanks to the information provided by OSMOS Hellas, the client is assured that the equipped structure is safe and informed as early as possible if any drift from the normalbehaviour occurs. By anticipating the damages, the client can optimize the maintenance of the Propylaia and protect this historical monument.
