|Swiss archaeologists studying mysterious shafts unearthed at the Roman site of Augusta Raurica believe the four-metre pits were designed as ancient refrigerators. They believe that Romans used shafts as cool stores during summer.|
The shafts were filled with snow and ice during winter and then covered with straw to keep the space cool well into the summer months, allowing everything from cheese to wine – and even oysters – to be preserved during warm weather.
|The most significant archaeological prize at Augusta Raurica is the spectacular silver treasure of Kaiseraugst.|
The hoard was found in 1961 and is presumed to have once been the property of a Roman commander.
