The small island Utö in the archipelago of Stockholm is famous for its iron ore. The ore was mined as early as the 12th century, and so this is the oldest iron mine of Sweden. Today there are traces of the mining era in the deep waterfilled mine holes, the big piles of mine tailings and Lurgatan with its old houses, 18th century, where the miners lived. In the small mining museum, open every day in summer, you can learn about the history of the mines and look at interesting collections from that time.

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.
