Abstract: A net  in a Banach lattice  is said to be unbounded norm convergent or un-convergent to  if  for all . In this talk, we investigate un-topology, i.e., the topology that corresponds to un-convergence. We will see that un- topology agrees with the norm topology iff  has a strong unit. Un-topology is metrizable iff  has a quasi-interior point. Suppose that  is order continuous, then un-topology is locally convex iff  is atomic. An order continuous Banach lattice   is a KB-space iff its closed unit ball  is un-complete. For a Banach lattice,  is un-compact iff  is an atomic KB-space.
