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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
