I set up and argue for a novel view in the metaphysics of spacetime: dynamical substantivalism. Dynamical substantivalism results from treating as orthogonal two easily conflated questions. First, the question of whether there are immaterial spacetime points. Second, the question of what grounds spatiotemporal geometric structure. Dynamical substantivalism sides with the substantivalist on the former question, and with the dynamical theorist on the latter. I argue that dynamical substantivalism should be treated as a serious contender in the metaphysics of space and time.
