The Imatrankoski Rapids has been a famous tourist sight since the 18th century. For example Catherine the Great, the Empress of All the Russias, visited Imatra in July 1772. In 1892 the railway came to Imatra, which immediately shortened the journey from St. Petersburg and increased the influx of tourists. There were originally two wooden hotels used by Russian aristocracy, but but they had been destroyed in fires in the beginning of the 20th century.
The Grand Hotel Cascade d'Imatra (Valtionhotelli in Finnish) was opened in 1903. The huge jugend style castel hotel was designed by Usko Nyström and it represents the romantic medieval knight castle style (like the Neuschwanstein castle in Germany).
After Finland's independence in 1917, the Russians found themselves barred from crossing the border and the remote location of the Imatrankoski Rapids near the Russian border no longer held any attraction to Finnish tourists. The 1920s saw the construction of the Imatrankoski power station; after that, the rapids were allowed to surge free only for special shows.
Valtionhotelli was renovated to the original outfit in 1987. Today it functions as a Spa Hotel owned by Restel Oy.

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.
