The Vätteryd grave field, also known as Vätterydshed, dates from the Iron Age. The grave field consists of 183 menhirs, 15 stone ships - the largest 25 m long and 8 m wide - and 2 circles. Many of the stone ships are so damaged that all that remains are parts smaller than half the original size.
In the beginning of the 19th century, Vätteryd, with about 600 menhirs, was considered the largest grave field in Scandinavia. The research conducted between 1955 and 1957 made clear that the site had been a place of cremation burials. The grave goods found - such as bronze jewelry, glass and bronze pearls, and bronze wire - were taken to various museums in Stockholm.
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.
