They live in the integer cohomology of the base space and measure, in a sense complementary to the Stiefel-Whitney classes, the twisting of real bundles that persists even after accounting for Z/2Z obstructions. Where Stiefel-Whitney classes detect parity anomalies, Pontryagin classes detect the integral curvature information encoded in the bundles connect...)
