The Ice House at Ham House - a National Trust property - is unusual in three regards. Firstly, it is situated very close to the house, without tree cover, rather than in the wider estate which is more often the case. Secondly, the outside of the dome is covered in concrete - believed to be a World War II addition when the Ice House was used as an air-raid shelter. Lastly,the entrance passage is to the west, rather than the north which is the norm to avoid direct sunlight.
The Ice House dates from the 18th century and is Grade II listed. The entrance passage and lighted interior can be viewed as part of the standard property admission.
