In the Chern-Simons formulation of Einstein gravity in 2+1 dimensions the
phase space of gravity is the moduli space of flat G-connections, where G is a
typically non-compact Lie group which depends on the signature of space-time
and the cosmological constant. For Euclidean signature and vanishing
cosmological constant, G is the three-dimensional Euclidean group. For this
case the Poisson structure of the moduli space is given explicitly in terms of
a classical r-matrix. It is shown that the quantum R-matrix of the quantum
double D(SU(2)) provides a quantisation of that Poisson structure.
