The windowless square stone icehouse is perhaps the most unusual structure on the Glen Rose courthouse square. With its heavy, iron-banded, insulated wooden door and sloping shed roof, this storage building was built about 1930. Its purpose was to conserve ice in 50- and 100-pound blocks transported from ice-making plants elsewhere. Long-time Glen Rose residents remember paying for ice from this storage building at the feed store next-door. At home consumers kept perishable foods cool in ice boxes or used it in crank-style ice cream freezers.
