Skansen is the first open air museum and zoo in Sweden. It was founded in 1891 by Artur Hazelius (1833-1901) to show the way of life in the different parts of Sweden before the industrial era. Skansen attracts more than 1.3 million visitors each year. The many exhibits over the 75 acre (300,000 m²) site include a full replica of an average 19th-century town, in which craftsmen in traditional dress such as tanners, shoemakers, silversmiths, bakers and glass-blowers demonstrate their skills in period surroundings.
There is even a small patch growing tobacco used for the making of cigarettes. There is also an open-air zoo containing a wide range of Scandinavian animals including the bison, brown bear, moose, grey seal, lynx, otter,red fox, reindeer, wolf, and wolverine (as well as some non-Scandinavian animals due to their popularity). There are also farmsteads where rare breeds of farm animals can be seen. In early December the site's central Bollnäs square is host to a popular Christmas market that has been held since 1903, attracting around 25,000 visitors each weekend. In the summer there are displays of folk dancing and concerts.
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.
