The first written record of Raikküla manor date back to the year 1469. Later it has been associated with the von Staals, the Kankrins and the von Keyserlings. The luxurious High-Classicist main building was completed on the foundation of a former building in 1820. After a fire in 1960, the house lied in ruins for a long time. Currently, it is privately owned and being renovated. About a kilometre from the manor's centre is a family graveyard of the von Keyserling's family.

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.
