Finished in 1259, Stolzenfels was used to protect the toll station at the Rhine, where the ships, back then were the main transport for goods, had to stop and pay toll. Over the years it was extended several times, occupied by French and Swedish troops in the Thirty Years' War and finally, in 1689, destroyed by the French during the Nine Years' War.
For 150 years the ruins decayed, until in 1815 they were given as a present to Frederick William IV of Prussia by the city of Koblenz. Following the romantic traditions, the prince started to completely rebuild the castle after 1826 as a summer residence. Supported by famous neoclassic architect Karl Friedrich Schinkel, the castle was completely remodeled in the then fashionable neo-Gothic style, aiming to create a romantic place representing the idea of medieval knighthood - the architects even created a tournament site.
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.
