Burn-down risk of seven architectural monuments in Kyoto-Higashiyama area due to post-earthquake fire spread was analyzed. The analysis was conducted by the Monte Carlo simulation using a physics-based urban fire spread model formerly developed by the authors. Factors of uncertainty considered in the present analysis were the conditions on: (1) outbreak of fire; (2) firefighting activity at initial stage of fire; (3) structural damage of individual buildings due to seismic motion; and (4) change of weather in time series. The result shows that burn-down risks of Rokuharamitsuji, Hokanji and Kenninji are rather close to the mean value of all the houses in the target urban area. The result indicates that no fire-stops are maintained between these architectural monuments and densely-built wooden houses in their surroundings. Thus, integrated approach involving entire urban area is required on implementing fire safety measure in order to effectively reduce the burn-down risk of the architectural monuments.
