The last Sunday of the month gathers nice sellers of candlesticks, furniture, paintings, mirrors, watches, books, shoes, lace and other antique items at the Castle. Today there is a square there, while before the war there was a street. This street was called Szeroka and it was about it that the Seer of Lublin said that it was the center of the universe. During the Lublin Old Exchange, when the square is filled with porcelain, furniture, buttons, uniforms, road signs and coins, it is not hard to believe.
