Isospectral Riemann surfaces

We construct new examples of compact Riemann surfaces which are non isometric but have the same spectrum of the Laplacian. Examples are given for genus $g=5$ and for all $gge 7$. In a second part we give examples of isospectral non isometric surfaces in $bbfRsp 3$ which are realizable by paper models.
