Where is
Francisco Balagtas buried? His grave, it seems to me, is a pilgrimage-worthy site especially given his stature in Philippine literature, but I've never heard it mentioned before, and Google offers almost no clues.
Assuming he was buried in the town's public cemetery, there is little chance that his grave survives, owing to that habit of public cemeteries digging up the dead after 50 or so years and cremating the remains or reburying them in mass graves. (For that reason, you do not see any graves of Filipinos who died before the 1860s or so) There perhaps would be a better chance if he were interred inside a church, but considering his anti-clerical bent, chances are Balagtas would not have consented to be buried in one.
This would make a great documentary subject.
