The Glehn Castle or manor was established by Nikolai von Glehn on the northern part of the lands of his Jälgimäe Manor to become his new residence. The castle was completed in 1886 and was designed by himself. The castle is surrounded by a park with several buildings like palm house (1900–1910), observatory tower (1910) and sculptures Kalevipoeg (1908), Crocodile (1908), all of those designed by Glehn himself.
After Glehn emigrated to Germany in 1918 the castle was looted and fell into decline. In the 1960s, restoration of the building commenced. The renovated palace was inaugurated on the 24 March 1977.
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.
