  We introduce a gauge invariant definition of a monopole on the lattice. The
construction is based on the observation that for each Wilson loop there exists
an extra U(1) group which leaves the loop invariant. Since the lattice
formulation utilizes the language of Wilson loops, the definition of the
monopole charge in terms of this plaquette dependent U(1) is gauge invariant.
The explicit construction of gauge invariant monopoles is presented both in
continuum and on the lattice.
