Several cycles of freeze and thaw easily destroy a porous stone such as tuff which is often used for sculptures and buildings in Japan. One of the ways to protect stone objects from such destruction is to shelter them. The authors studied the effect of a sheltering construction (temple) for stone sculptures of Buddha at Ohya in Tochigi Prefecture. As the temperature of the stone surface in the temple was almost constant while the outside temperature fell below freezing point, the sheltering construction was effective in protecting the stone sculptures from their destruction by the freeze-thaw cycle.
