Following the example many established cities Vilnius was granted the Magdeburg Rights. Those rights granted a right for merchants on the routes through Vilnius to stop in the capital and to sell their goods in a market. In 1503, due to the number of foreign traders the city built a special guest house for them to stay, on the site of the present day National Philharmonic. They had rooms for merchants and their retinues and premises to store their goods as well as room for horses, carts and sledges. Strict regulations were also imposed on traders and guilds regarding the construction of their market places and participation in the city's events.
