Home to a radio and weather observatory
Chilbolton Observatory sits on the site of a disused RAF airfield next to the village, operated by a national scientific research body rather than any local business, and its large steerable radar dish is a distinctive landmark visible for some distance around.
Part of the Test Valley district
Chilbolton falls within Test Valley, so applications here are decided by the borough's own planning service, the same as neighbouring Wherwell and Stockbridge.

Open countryside around the village
Away from the observatory site, Chilbolton is surrounded by open farmland and chalk downland typical of the upper Test valley, with more rural, larger plots than in the busier villages closer to Winchester.
