The Čachtice castle ruins stands on a hill featuring rare plants, and has been declared a national nature reserve for this reason. The castle was a residence and later the prison of the Countess Elizabeth Báthory, who is alleged to have been the world's most prolific female serial killer.
Čachtice was built in the mid-13th century by Kazimir from the Hont-Pázmány gens as a sentry on the road to Moravia. Later, it belonged to Máté Csák, the Stibor family, and then to the famous Bloody Lady Elizabeth Báthory. Čachtice, its surrounding lands and villages, was a wedding gift from the Nádasdy family upon Elizabeth's marriage to Ferenc Nádasdy in 1575.
Originally, Čachtice was a Romanesque castle with an interesting horseshoe shaped residence tower. It was turned into a Gothic castle later and its size was increased in the 15th and 16th centuries. A Renaissance renovation followed in the 17th century. Finally, in 1708 the castle was captured and plundered by the rebels of Ferenc II Rákoci (Francis II Rákóczi). It has been in decay since.
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.
