In this expository article we discuss some ideas and results which might lead to a theory of infinite dimensional symmetric spaces $\hat{G}/\hat{K}$ where $\hat{G}$ is an affine Kac–Moody group and $\hat{K}$ the fixed point group of an involution (of the second kind). We point out several striking similarities of these spaces with their finite dimensional counterparts and discuss their geometry. Furthermore we sketch a classification and show that they are essentially in 1 : 1 correspondence with hyperpolar actions on compact simple Lie groups.
