The Elephant's Rock is a large boulder of trachyte and andesite, eroded by the atmospheric agents that gave it the shape of an elephant. It is about 4 meters high. The rock is located near Castelsardo, to the left of the old road that led from the hamlet of Multeddu to the village of Sedini.
The Elephant's Rock has a great archaeological importance, because two domus de janas, ancient tombs dating back to the pre-nuragic period, have been carved inside.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
