We determine the topological susceptibility in the SU(3) pure gauge theory. We perform a series of high-statistics lattice studies and take the combined continuum and infinite volume limit. We find χtopr 04 ≤ 0.0524(7)(6), which translates into χtop1/4 ≤ 193(1)(8)MeV with the second error exclusively due to the intrinsic scale ambiguity.
