The Torres de Quart is one of the two remaining gates of the old Valencia city wall. It was built between 1441 and 1493 to the site of 11th century Moorish gate.
Over the subsequent centuries, the city of València was not placed under siege. While the walls of the city were in disrepair, the towers continued to be anchor points in the defense of the city. In the 17th century, the tower was also being used as a women's prison, with many inmates being prostitutes. In 1808, during the Battle of Valencia in the Peninsular War, cannonballs and bullets from French troops damaged the gate. The holes were preserved during future restorations as a memory of the occasion.
The gate was declared a national monument in 1931. It has undergone several restorations and now serves as a tourist attraction.
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.
