The Kaluza-Klein monopole is a well known object in both gravity and stringtheory, related by T-duality to a "smeared" NS5-brane which retains theisometry around the duality circle. As the true NS5-brane solution is localizedat a point on the circle, duality implies that the Kaluza-Klein monopole shouldshow some corresponding behavior. In this paper, we express the Kaluza-Kleinmonopole as a gauged linear sigma model in two dimensions and show thatworldsheet instantons give corrections to its geometry. These corrections canbe understood as a localization in "winding space" which could be probed bystrings with winding charge around the circle.Comment: 20 pages, REVTeX, v2: minor equation correctio
