Rokycany is a town in the Plzeň Region of the Czech Republic. It lies 17 km (11 mi) to the East from the region capital of Plzeň on the confluence of the River Klabava and the Holoubkov Brook. Alternatively, the Holoubkovský potok is referred to as the Borecký potok and the section of the Klabava River down to the confluence as the Padrťský potok. There is another smaller brook in the western part of the town.
The town is located in the lowland, 362 metres above sea-level, bordered by hilly woodlands, especially the Brdy mountains to the east (highest elevation – Tok, 865 metres above sea-level) or the Radeč massif – 718 metres above sea-level. Rokycany is also the seat of the Municipality with Extended Competence and Municipality with Commissioned Local Authority.
Rokycany is officially divided into 4 districts, namely “Střed” (Center), “Nové Město” (New Town), “Plzeňské předměstí” (Plzeň Suburb) and “Borek”. 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 On the southern side the walls have been replaced by a representative avenue (Jiráskova ulice) with several major public buildings such as “sokolovna” (Sokol organization headquarters) from 1903, new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. Nové Město is by far most populous district surrounding the historical core from north, east and south. It evolved from traditional Pražské předměstí suburb which was located on both banks of the Klabava river along the road to Prague (Pražská ulice) and Nerudovo náměstí square. Plzeňské předměstí forms western part of Rokycany. It started in medieval era as a small cluster of rural houses adjoining Rokycany’s historical core. In early 17th century Protestant church Nejsvětější Trojice was built here, soon after taken by Catholics. In 19th century Plzeňské předměstí quickly grew along the road to Plzeň (Plzeňská ulice), mainly industrial development was later accompanied by residential houses. In 1920s massive housing project started on Rokycany’s southern outskirts. The new neighbourhood was later called Rašínov. It consists solely of private houses in art-deco style. In 1930’s another neighborhood was inaugurated in the western periphery, called . It also features almost exclusively private residential houses. Borek is formerly independent village located ca.2 km east of Rokycany. In 1960 Borek came under the jurisdiction of Rokycany. The Borecký rybník lake is most notorious landmark of this district. In 20th century the built-up area of Borek expanded amalgamating the village with Rokycany.
