It is beyond doubt that heritage buildings are a fundamental expression of the richness and diversity of the world's states' cultures. To preserve heritage buildings, state-of-the-art recommendations suggest monitoring progressive damage in real-time and/or simulating different scenarios numerically. To avoid massive destructing testing on masonry structures, the most rational implementation of digital twinning would be to develop digital tools and numerical models able to simulate several scenarios. Thus, computational results must be stored and analysed using statistical methods to provide decision-making tools that would drive stakeholders to a rational approach. This paper presents a selection of computational strategies that can be used in the seismic analysis of URM structures. The first two approaches utilised the discrete element method (DEM) and the finite element method (FEM). Then, analytical approaches based on the Limit Analysis (LA) theory, i.e. micro and macro LA, were also adopted to perform numerical predictions of the structural behaviour. Finally, some cross-linked considerations regarding the information arising from NDT testing, their cost and the development of a reliable numerical assessment in a Digital Twin framework are provided.
