<p>Can every topological (not necessarily smooth or PL) manifold be given the structure of a CW complex?</p>
<p>I'm pretty sure that the answer is yes. However, I have not managed to find a reference for this.</p>

<p>The result is that compact topological manifolds have the homotopy-type of CW-complexes, to be precise. </p>
