The Sant Antoni Castle is located in the Spanish village of Fornells, in the municipality of Es Mercadal. It was built in the 17th century in the local harbour and due to this building, the town was born.
Only some ruins are left from the structure, as it was dismantled by the Spanish after the British domination, just like St. Philip's Castle. Not far from there, there is the Fornells Tower, a defensive tower whose objective was protecting the castle from enemy attacks.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
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.
