Preservation of architectural heritage is considered a fundamental issue in the cultural life of modern societies. This heritage is accumulating damage due to deterioration of materials, repeated loading and exceptional events. This means that conservation, repair and strengthening are often necessary. In this process, monitoring and non-destructive testing play a major role, providing information on the building condition and existing damage, and allowing to define adequate remedial measures. Dynamic based methods are an attractive tool because they are non-destructive and are able to capture the global structural behaviour. The present paper focuses on different aspects related to vibration analysis, namely exploring damage, environmental effects on the dynamic response, a comparison between commercial wireless based platforms and conventional wired based systems, and a novel wireless based system
