Because of its central location, the island has been important to the communications and commerce in the region. The settlement of Nötö has been dated to the early 11th century, and the assumption is that vikings stopped by during their travels and possibly even settled on the island.
A culturally and historically valuable village consisting of old farms ('hemman') still exists on the island. In the centre of the village there is a windmill, and a few minutes away from the village harbour there is a chapel, inaugurated in 1757. During the summer season, there is a cafeteria in the old primary school building, where e.g. various art exhibitions are held.
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.
