It is known that: \begin{itemize} \item the combinatorics of a simple convex polytope can be recovered by its \(1\)-skeleton; \item a \(d\)-dimensional simplicial manifold can be recovered by its \((\lfloor \frac{d}{2}\rfloor +1)\)-skeleton. \end{itemize} It is proven in the paper that any \(d\)-dimensional cubical homology manifold embeddable in a cube can be reconstructed from its \((\lfloor \frac{d}{2}\rfloor +1)\)-skeleton. Under some additional conditions the result can be tightened to the \(\lceil \frac{d}{2}\rceil\)-skeleton.
