A Besicovitch set is a set which contains a unit line segment in any direction. It is known that the Minkowski and Hausdorfi dimensions of such a set must be greater than or equal to 5= 2i n 3 . In this paper we show that the Minkowski dimension must in fact be greater than 5= 2+ for some absolute constant > 0. One observation arising from the argument is that Besicovitch sets of near-minimal dimension have to satisfy certain strong properties, which we call \stickiness, \planiness, and \graininess.
