In the 13th century, the San Juan del Hospital Church was the priory of the Knights of the Order of St. John of Jerusalem with a hospital attached and it was converted into a military parish in the 18th century. Built around 1261, it is considered to be the first church built after the Christian conquest. Its combination of the synthesis and elegance of Romanesque tradition with the new gothic architecture and the fact that it has the only cemetery dating from medieval times in Valencia, led to its classification as a National Historic and Artistic Monument in 1942.

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.
