měnírna Rokoska Trafostation
Rokoska in the Prague part of Libeň is a former tram changer from 1937 to 1940. The building used to provide electricity for tram lines to Devils and Kobylis as well as for Hospital Na Bulovce. It is an important part of the historical infrastructure of Prague transport.
The building was designed by the architect Eduard Hnilička and built by František Strnada between 1937 and 1940. The creation of the building was linked to the intensive development of urban transport and the expansion of the electricity network in Prague. At that time, the modernization of tram connections took place in the new parts of the city, including the introduction of transport to Kobylis in the late 1930s, which was allowed by the construction of the road Kobylisa and the introduction of trams by the streets of V Holešovice.
The construction was fully automated and remotely operated from the holesovice plant. Its main task was to convert alternating current into direct current for trams. For this purpose, two mercury rectifiers were originally used to adjust the input AC voltage of 6 kV and 22 kV to a DC voltage of 600 V.
In 1968, there was a technological modernization whereby mercury rectifiers were replaced by semiconductor devices. The exchange room served its original purpose until 1996. A year later, it was disabled and replaced by new Rokoska and Trojská changers.
Object in the street In Holešovice near the crossroads The breeder is currently without use, even though it was previously considered to set up the exposure of PRE a.s. There is currently a procedure for the declaration of construction by the cultural monument of the Czech Republic.
This technical monument commemorates the era of development of Prague's electrical engineering and urban mobility. It is an interesting goal for anyone interested in industrial architecture and the history of transport in the capital.

Welcome to the site with a rich history and unique architectural character - we are facing the former tram changer Rokoska in Libni. This object, which initially seems simple, hides behind its walls a fascinating story of technical progress and history of Prague transport.
The Rokoska Exchange was built between 1937 and 1940 according to the design of architect Eduard Hnilicek. Its purpose was to provide electricity for the tram lines that dragged to Devils and Kobylis, as well as for the hospital Na Bulovce. This building is a key part of the infrastructure that supported the development of the city during the 20th century.
Look up and you will see the elegant line of the roof and the symmetrical arrangement of the window lines, which are the characteristic features of the architecture of that time. Note also the robust wall construction that shows their function as a technical object dedicated to safety and reliability.
In 1968 there was a significant change of currency - the exchange of mercury rectifiers for semiconductor devices was carried out. This progress was another step forward in technology and traffic efficiency. Rokoska fully automated operated remotely controlled from the holešovice power plant, which was a very advanced solution for its time.
Let's move on to the key stories related to this place. Eduard Hnilička, an architect who designs this object, is one of the great personalities of Czech architecture of the 20th century. His work on changing Rokoska shows his ability to combine functionality with aesthetic attraction.
The interesting thing is that although the changer stopped its operation in 1997 and was disabled, its history and architecture continue to inspire. It is a reminder of a time when technological progress has had profound consequences for everyday life.
Now pay attention to the surrounding environment and consider how this building has become an integral part of Libne's history. Think about the people who worked here and the technological progress that was possible through their efforts.
