During the centuries of German economic domination, the guilds were Riga's power brokers. The former, dating from 1384, was the home of the merchants, while the latter held the city's artisans. These slightly different audiences are reflected in the respective usage of the buildings today: while the Great Guild is home to the Latvian Symphony Orchestra, its smaller cousin hosts conferences and the occasional disco. The Small Guild is now also open to the public during the day for a small admission fee of 1Ls.
References: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.
