Střed encompasses the historical core of the town with two main squares, main church of Panna Marie Sněžná and town-hall. Since 1992 the historical core of Rokycany has been declared protected zone in order to protect the architecture. The border of this district largely follows the path of former town's fortification. The medieval walls are still standing in several short sections. On the southern side the walls have been replaced by a representative avenue (Jiráskova ulice) with several major public buildings such as "sokolovna" (Sokol organization headquarters) from 1903, new railway-station from 1931, gymnázium (grammar-school) from 1905 or municipal bank from 1933.
