Ancient masonry constructions form a very important part of the tangible cultural heritage. They constitute records of the history and the building technology of different cultures and encompass important artistic heritage. Additionally, in many cases they still form a part of the servicing infrastructure of the modern communities by either maintaining their original use, such as churches and bridges, or by acquiring new one like museums.

Over the years, such structures, inevitably exhibit damage that makes them vulnerable against seismic actions and retrofitting interventions become necessary. Having undertaken important projects on the retrofitting of several historical structures, we have the required know-how in the analysis and assessment of the current condition of an existing structure, as well as, in the design and realization of effective strengthening interventions.
