Count Wilhelm II of Katzenelnbogen built the Katz Castle in the second half of the 14th century. Katz Castle was used as bastion and military base to protect the Rheinfels Castle. Together they formed a fortified bulwark with a barrier for levying of the Rhine toll. The extended view up to the bend of the river at the Loreley was also of great importance to secure salmon fishing. Due to the intentionally chosen location on the mountain ridge Katz Castle could not possibly be conquered from the valley.
Only after the invention of fire arms, Katz Castle had to be substantially reinforced. It was also upgraded as bastion against Maus Castle in the Electorate of Trier. At the same time the donjon of Katz Castle was raised to to ensure eye contact with Reichenstein Castle. In 1479 the family line of the Counts of Katzenelnbogen died out.
In succession of long-lasting disputes on heritage, Katz Castle and Rheinfels Castle were besieged, demolished, rebuilt and extended several times. Even though repairs had been made in 1800, Napoleon blew up Katz Castle in 1806.

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.
