Gräfsnäs Castle today consists of a heavily restored main building with barred windows and surrounding dry moat. The ruins are remnants of the original palatial fortress built in Swedish-French Renaissance style. The castle, which met with such a tragic fate, was constructed in c. 1571 and belonged to many different owners (like Leijonhufvud, Sparre and Holstein-Augustenburg families) before it was finally abandoned in the late 19th century. The tragic coincidence was that Gräfsnäs was damaged by fire in every one hundred years (1634, 1734 and 1834).
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.
