Saint-Didier-de-la-Tour (in French pronounced as /sɛ̃ didje də la tuʁ/, literally Saint-Didier of La Tour) is a commune in the Isère department in southeastern France.[2] It is often referred to as "La Cassôla", after a spring in the village, which has heavily coloured waters.
Until the First World War, lignite mines were exploited near the village, employing over 600 people.
The Bourbre forms part of the commune's northeastern border.
