In this paper we consider generalized uncertainty principle (GUP) effects inhigher dimensional black hole spacetimes via a nonlocal gravity approach. Westudy three possible modifications of momentum space measure emerging from GUP,including the original Kempf-Mangano-Mann (KMM) proposal. By following the KMMmodel we derive a family of black hole spacetimes. The case of five spacetimedimensions is a special one. We found an exact black hole solution with aBarriola-Vilenkin monopole at the origin. This object turns out to be the endpoint of the black hole evaporation. Interestingly for smaller masses, we founda "naked monopole" rather than a generic naked singularity. We also show thatthe Carr-Lake-Casadio-Scardigli proposal leads to mild modifications ofspacetime metrics with respect to the Schwarzschild-Tangherlini solution.Finally, by demanding the same degree of convergence in the ultraviolet regimefor any spacetime dimension, we derive a family of black hole solutions thatfulfill the gravity self-completeness paradigm. The evaporation of such blackholes is characterized by a fluctuating luminosity, which we dub a lighthouseeffect.
