The authors present historical genesis of this territory in connection with the structure of the historical centre, and simultaneously they document the conservation of original medieval parceling up to the present. The authors summarize the opinions of the solution of the Obchodná street at the turn of the 19th and 20th century up to the end of the eighties when they actively participate in the solution. They deal with shifting in thinking in single developmental stages up to forming of the principles and criteria of the solution of the Obchodná street that ended by the first proposal of the regulation plan of this extremely valuable enclave of Bratislava.
