In this work we present a preliminary study of the seismic response of the Acropolis and of the Parthenon of Athens to the 1999 Mw 5.9 earthquake. The three-dimensional numerical model includes the surface topography of the Attica region, the seismogenic fault, and the most important geological units in the metropolitan area of Athens: the Acropolis hill and the Parthenon. The multiscale numerical model, designed in order to correctly propagate seismic waves up to $5Hz$, is solved through a discontinuous Galerkin spectral element method implemented in the open source library SPEED (speed.mox.polimi.it). Numerical results show the effectiveness of this approach and highlight new challenges for dynamic soil-structure interaction problems at the regional scale.
