The Otepää Maarja Lutheran Church was built in 1890 and represents the Gothic revival style. On 4th June 1884 the blue-black-white flag of the Estonian Students’ Society was consecrated in the church, which later on became the flag of the nation and in 1992 the official national flag of Estonia. The bas-reliefs of the flag, the author of which is sculptor Voldemar Mellik, were opened on the church wall in 1934 (on the 50th anniversary of the national flag). The bas-reliefs were destroyed in 1950 and restored by sculptor Mati Variku and opened again on 15th July 1989.
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.
