The Geological Park of Aliaga and the Paleontological Park of Galve constitute exceptional viewpoints over the last 200 million years of the earth and life history at the Iberian Chain. Witnesses left here by the geological evolution make interesting objects both for research and educational or touristic purposes.the Aliaga geopark includes 11 points and trails showing panels and signboards. Some of them offer panoramic views of the geological formations, tectonic structures and landforms. Others show details of continental and marine sediments, minerals and fossils, as well as spectacular folds and tectonic faults. The Galve parkis the dinosaur territory: a nice exposition of local fossils, a number of footprint sites and real-scale reconstructions of the most representative specimens. The projects have been developped by the municipalities of Aliaga and Galve with scientific support by the Department of Geology of the Zaragoza University. Both make a part of the Cultural Park of Maestrazgo, which provides legal support and protection for the natural and historical heritage of this region. The last also includes other neighbouring sites of interest: the exposition on coal mining activities at Santa Bárbara and the sculpture park of Hinojosa de Jarque.
