The properties of the downtown architectural and town-planning creation in the historical cities of Derazhne and Derazhnya are considered. It has been found that in Derazhne the castle was located in the southern part of today's village, on a wedge ledge formed at the place where the stream flows into the Horyn River. The downtown stood northeast of the castle. Its territory had features of a regular rectangle, and the gates were located on the western and northern sides. Unfortunately, today it is difficult to determine the location of the wooden Roman Catholic church in the downtown, instead, the brick church of the beginning of the 19th century was built on the territory of the castle. It was established that the castle in Deraznya was rectangular in plan with two corner roundels located in the southern and northern corners of the western side. The indistinct fragments of the downtown ramparts preserved to this day, the configuration of the streets and the graphic image of the urban defense complex of Deraznya on the map of the mid-17th century by the military engineer Guiyaume Levasseur de Beauplan indicate that the northern and eastern parts of the fortifications of the city center had bastion-like protrusions, and the northeastern corner had a special fortification purpose . Rynok Square was located in the center of the downtown. A wooden church stood in its northeastern corner, and a brick Roman Catholic church in the southeastern corner.

Relying on the determined properties of architectural and town-planning creation in the downtown of Derazhnye and Derazhnya settlements, we can record their equivalent historical and cultural value. The development vector of their cities was identical, but the architectural image was individual. The spatial composition of the connection between the castle and the city center, the abundance of temples and the fortification system differed. Instead, the street network in Derazne and Derazne was ordered, calculated and synchronized with two entrance gates.

The current state of the downtown is unsatisfactory. In Derazhnya, Khmelnytskyi region, the street network, quarters with several houses of the 19th century, and castle ramparts have been partially preserved. The downtown of Derazne, Rivne Oblast, has preserved parts of historic streets, completely lost quarters, and faint traces of the castle. In both settlements, uncontrolled green spaces hinder the spatial perception of the historical center.

Therefore, recommendations have been formulated for the return of service functions to the downtowns, their unification with the rest of the settlement territories, saturating them with new functions, and the reproduction of the traditional historical and urban landscape.
