The 12th-century late Romanesque church of San Juan Bautista is attached to a 10th-century Berber tower, which is 18 metres tall with a 9.4x7.4 metre floor plan and 1.75-metre thick walls on all of its three floors. Originally it was built with the rammed earth technique but then the structure was changed to stonework. The access door to the tower is hidden in a passageway that connects the tower to the church. Later on, the windows were opened up to place bells inside, and the tower was covered with a roof.
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.
