Žagarė is a town of rectangular shape with striking irregular elements of self-development. The rectangular plan was prepared in the second part of the 16th century when the two pats of the town were planned separately only changing their radial plan. There are some typical self-development elements left from the original period and the later ones as well. Because of the restoration of towns after the fires a network of streets and the square changed. The present plan of the town was almost completely formed until World War I. Scenery (river, mounds and forests) dominated at the beginning of development of both towns. Despite loses Žagarė is one of the most original small towns with its architecture and development of urbanistics. Architecture of Žagarė is valuable because of its organic whole and integrity of self-development and elements formed step-by-step. Shape of the town plan suits forms of the scenery and it determines the organic whole of Žagarė. The network of streets is rather winding along the Švėtė in both towns and in the north-east of Old Žagarė whereas streets were straight in other part of the territory. Two main streets of Žagarė interlink in knots on both banks of the Švėtė and market squares were built there. It also makes Žagarė peculiar. Red brick cottages and two-storey houses built after the fires of 1881, 1909 and 1911 influenced architecture of Žagarė. These buildings made the town particular.
