We study magnetically charged classical solutions of a spontaneously broken gauge theory interacting with gravity. We show that nonsingular monopole solutions exist only if the Higgs-field vacuum expectation value {ital v} is less than or equal to a critical value {ital v}{sub cr}, which is of the order of the Planck mass. In the limiting case, the monopole becomes a black hole, with the region outside the horizon described by the critical Reissner-Nordstroem solution. For {ital v}{lt}{ital v}{sub cr}, we find additional solutions which are singular at {ital r}=0, but which have this singularity hidden within a horizon. These have nontrivial matter fields outside the horizon, and may be interpreted as small black holes lying within a magnetic monopole. The nature of these solutions as a function of {ital v} and of the total mass {ital M} and their relation to the Reissner-Nordstroem solutions are discussed.
