  Nanophotonics offers a promising range of applications spanning from the
development of efficient solar cells to quantum communications and biosensing.
However, the ability to efficiently couple fluorescent emitters with
nanostructured materials requires to probe light-matter interactions at
subwavelength resolution, which remains experimentally challenging. Here, we
introduce an approach to perform super-resolved fluorescence lifetime
measurements on samples that are densely labelled with photo-activatable
fluorescent molecules. The simultaneous measurement of the position and the
decay rate of the molecules provides a direct access to the local density of
states (LDOS) at the nanoscale. We experimentally demonstrate the performance
of the technique by studying the LDOS variations induced in the near field of a
silver nanowire, and we show via a Cram\'er-Rao analysis that the proposed
experimental setup enables a single-molecule localisation precision of 6 nm.
