Since 1907 the Parliament of Finland was convened in House of the Estates and Finnish House of Nobility. Both buildings became however too small for the 200 members of the independent Finland Parliament. In 1923 a competition was held to choose a site for a new Parliament House. Arkadianmäki, a hill beside what is now Mannerheimintie, was chosen as the best site.
The architectural competition which was held in 1924 was won by the firm of Borg–Sirén–Åberg. Johan Sigfrid Sirén was given the task of designing Parliament House. The building was constructed 1926–1931 and was officially inaugurated on March 7, 1931. Ever since then, and especially during the Winter War and Continuation War, it has been the scene of many key moments in the nation's political life.
Sirén designed Parliament House in an architectural style combining Neoclassicism with early twentieth century modernism. The exterior is red granite and the façade is lined by fourteen columns with Corinthian capitals. The building has five floors, each of which is unique. The floors are connected by a white marble staircase and famous paternoster lifts. Most important for visitors are the main lobby, the stately Session Hall and the large Hall of State.
Guided tours are arranged in Parliament house. Tuesdays and Fridays you can watch the Parliament in session from the public balcony.
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.
