Frankenberg Castle was constructed during the 13th century and historically it was the seat of a Vogt, local administrator. Until the end of the 19th century, the castle consisted of a broad forecastle, a farmyard, and a main castle (which was completely surrounded by water).
With the introduction of the French Constitution of 1793, Frankenberg Castle lost its status as a fief of Jülich. Between 1834 and 1838, the property underwent comprehensive renovation and modernization.

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.
