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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
