Kultaranta (Golden beach) is the summer residence of the President of Finland. The granite manor house was built by Alfred Kordelin in 1913-16. Kordelin was an industrialist, businessman and one of the richest Finnish entrepreneurs of his time. He was kidnapped by a group of Red Guards and murdered by a Russian sailor on 7 November 1917. Kordelin was childless and the manor's ownership shifted to the University of Turku. In 1922, the Finnish Parliament voted to acquire it for use as the president's summer residence.
Kultaranta was designed by the famous architect Lars Sonck. It’s surrounded by 560,000 square metres of park, belonging to the property. The parks around the manor, containing approximately a thousand square metres of greenhouse and a garden with 3500 roses called Medaljonki ('medallion'), are open to the public. Tours in the garden are organised by the City of Naantali's tourist service.

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.
