In this paper, we obtain classification of the topological holonomy groups in SO(3). Such a group is given by one of the following: a finite group (such groups are classified by Klein); a commutative infinite group which is generated by one or two elements, and dense in a subgroup of SO(3) isomorphic to SO(2); a non-commutative infinite group generated by two elements of order 2, ∞ such that these rotation axes are orthogonal; a non-commutative infinite group which is dense in SO(3).
