The Hossa Värikallio rock paintings are amongst the largest prehistoric rock paintings in Finland. The pictures on the rock wall rising from Lake Somerjärvi were painted in the Stone Age, i.e. about 3,500 - 4,500 years ago.
Paintings were painted from a boat or when standing on the ice of the lake. On the surface of the rock wall there are 61 separate figures depicting scenes of hunting and shamanic rituals. The paintings have probably been used for marking a route or describing events.
Värikallio is accessible all year round. In summer there is a trail leading to the paintings, and an observation platform has been built in front of the cliffs. In winter there is a skiing trail to the cliffs and a snowmobile trail nearby. The access to the paintings is free-of-charge. Theme guiding for groups is subject to a charge.
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.
