We develop a new approach to, and somewhat extend, results of Cheeger, Colding and Tian (Geom. Funct. Anal. 12 (2002) 873–914), which give restrictions on the singular sets that can arise as Gromov‐Hausdorff limits in the presence of integral bounds on the curvature. The foundation of this approach is provided by a rigidity result for flat singular spaces, which has independent interest.
