The Tallinn Song Stage (Lauluväljak) was built in 1959 for the Estonian Song Festival. The stage was meant to hold over 15,000 singers but it’s also possible to use it the other way – the performance will take place in front of the stage and audience is sitting on the stage.
The stage was the main places of the Estonian revolution and new independence in 1988-1991. Estonians gathered there to sing patriotic hymns in what became known as the Singing Revolution that led to the overthrow of Soviet rule.
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.
