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 Arch of Constantine is situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98-117), Hadrian (117-138) and Marcus Aurelius (161-180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
