  By explicit construction, we show that one can in a simple way introduce and
measure gravitational holonomies and Wilson loops in lattice formulations of
nonperturbative quantum gravity based on (Causal) Dynamical Triangulations. We
use this set-up to investigate a class of Wilson line observables associated
with the world line of a point particle coupled to quantum gravity, and deduce
from their expectation values that the underlying holonomies cover the group
manifold of SO(4) uniformly
