Thomas Hardy's ashes were buried in Westminster Abbey, in Poets' Corner, and his heart was buried in Stinsford in Dorset, alongside the grave of his first wife (and Cecil Day-Lewis, curiously). Unfortunately there persists a rumour that, after being extracted but before being buried, his heart was accidentally eaten by a cat, which, honestly, I rather think Hardy would have found pretty funny.
