We construct supergravity solutions that correspond to N $\mathrm{D}p$-branes coinciding with $\overline{N}$ $\overline{\mathrm{D}p}$-branes. We study the physical properties of the solutions and analyze the supergravity description of tachyon condensation. We construct an interpolation between the brane-antibrane solution and the Schwarzschild solution and discuss its possible application to the study of non-supersymmetric black holes.
