This short paper explores the possibility of conducting high-performance computing simulations of complex fire propagation in buildings of archaeological interest. The simulation protocol described here involves several steps: i) the geometric modelling of the buildings, ii) the mathematical modelling of combustion and fire propagation, iii) the numerical simulation using a Large Eddy Scale approach on parallel systems and iv) the real time rendering of the simulation data. Numerical examples are provided to emphasize the e ciency of the approach and its importance in supporting research in archaeology and validating hypotheses through simulation.
