  We propose a toy model of quantum gravity in two dimensions with Euclidean
signature. The model is given by a kind of discretization which is different
from the dynamical triangulation. We show that there exists a continuum limit
and we can calculate some physical quantities such as the expectation value of
the area, that is, the volume of the two dimensional euclidean space-time. We
also consider the extensions of the model to higher dimensions.
