The ruins of Ramstein Castle stand on a 182-metre-high, Bunter sandstone rock on the edge of the Meulenwald forest in the lower, steep-sided Kyll valley near Kordel.
The hill castle was built in the early 14th century by the Archbishop of Trier, Diether of Nassau as the successor to a fortified manor farm. From then on, it was a fief castle of the Electorate of Trier which was enfeoffed (subleased) to electoral subjects and cathedral deans. During the War of the Palatine Succession, the castle was occupied by French troops and largely blown up in 1689. The great damage was not repaired. However, tall sections of curtain walls, elements of corner towers and almost of all the exterior and the stone staircases of its medieval tower house stand.
Three larger-footprint modern buildings including a hotel-restaurant are on the southern part of the east-facing promontory. The hotel's outdoor terrace overlooks the lightly or densely wooded valley, depending on direction views. Fields have likely long stood next to the near-bend of the river enabling a clear view to the impassably sheer hillside (on horseback) on the opposite bank and intervening north–south route.
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.
