Graves of well-known Chess Masters and Chess Personalities
Another page which deals with gravesites of chess masters is Edward Winter's compilation Chess Explorations (8) - Graves of Chess Masters.
A nice booklet on "chess graves" was published 5 years ago in the Netherlands:
Rob Bijpost, Fred van der Vliet: Schaakgraven. Schaakkoerier no. 82. Motiefgroep Schaken (ed./publ.), 2006, 44 pp.
Here the cover of the booklet as PDF. The contents is also given on http://www.euwe.nl/koerier82-thema.htm.
