Abstract
Fix g > 1. Every graph of large enough tree-width contains a g× g grid as a minor; but here we prove that every four-edge-connected graph of large enough tree-width contains a g× g grid as an immersion (and hence contains any fixed graph with maximum degree at most four as an immersion). This result has a number of applications.
