We report the first realization of columnar defects in Co-dopedBaFe$_{2}$As$_{2}$ single crystals by heavy-iron irradiation. The columnardefects are confirmed by transmission electron microscopy and their density isabout 40 % of the irradiation dose. Magneto-optical imaging and bulkmagnetization measurements reveal that the critical current density is stronglyenhanced in the irradiated region. We also find that vortex creep rates arestrongly suppressed by the columnar defects. We compare the effect of heavy-ionirradiation into Co-doped BaFe$_{2}$As$_{2}$ and cuprate superconductors.
