sightseeing and other adventures in running shoes



Interesting and exciting things to see and do when visiting Slovakia – place of my origins.

Bedrich Schnirch. The first suspended steel roof.

I have been thinking about posting another recipe of a granola but then I have decided to write about more interesting topic this evening. I have noticed that I have not written about anything serious in a long time. Finally, a perfect idea crossed my mind yesterday. A lot of you guys liked the article on the folk architecture in Cicmany [link] and I thought I will do another piece on something very close to my heart. In the course of my studies, every time I attended a class where we were supposed to compose a paper, I have always been asigned to work on a topic with case study in Slovakia. To be honest, it is not an easy task to do especially if you have spent your college time aborad. I would usually have to look very hard to come up with something interesting. I have recently took a class ‘Design in existing context/ Renovation and alteration of architectural heritage’. It was a very interesting subject and I have learnt a lot about the industrial heritage – suspension bridges from the end of 19th century in particular. Anyway, I was supposed to write a short paper concearning a related topic. My problem was, Slovakia used to be quite agricultural land and the industrial revolution arrived very late, so I was short on interesting objects. There were no preserved suspension bridges to write about. However, I have accidentally stumbled upon an engineer Bedrich Schnirch and the rest of the paper came together very easily.

Bedrich Schnirch (in German literature Friedrich Schnirch, 1791-1868) was a czech engineer, inventor, and architect. He is known for designing the first suspended bridge on the european land as well as designign the first suspended bridge for a railway traffic. However, only few sources mention his work on the field of suspended roof constructions, neither do they mention his patent of a chain roof form 1826. Schnirch started designing and building bridges in Czech Republic, it used to be a part of Austria-Hungary back then, just like Slovakia, and later on moved to Vienna. The most of the bridges he had designed have been replaced over the time but there is one last from 1847 in Podolsko. It has been translocated to a new place, Stadlec, in the 1980s but it is still in use.[1] Considering the slow progress of industrial revolution in Slovakia, the time Schnirch has been working on his significant projects, all his structures vere build exclusively out of wrought iron. [2] The first puddling oven in Slovakia has been put into use in 1839. So, in his early projects, Schnirch was definitely using handmade steel parts. In the paper written on 10/1824 he describes several parameters of those emelents, e.g. the thinner the part was, the better strength the material performed in the experiments – comparing the determined overall tensile strenght of the mateial. The article (in German [3]) is looking at a hypothetical construction for a theatre, covered by a chain-roof, presenting a contemporary calculations concearning its load bearing behaviour. It is questionable, wheather was Schnirch fully aware of the Navier´s theoretical work on suspended construtions composed in 1823 [4] when composing this article. It could have been based on his own experience aquiried during planing and construction the bridge in 1823-24 in Staznice, span 29.71m.[5] Nevertheless, Schnirch introduced here the term suspended roof construction and has also registered a patent on the small chain-roofs. He presented this solution as a fire-resistant construction, as it would withstand fire for much longer than just a plain timber skeleton. According to the literature, by the end of 1820s, this solution has been implemented on five/six objects – Straznice, Tuřany na Morave, probably two structures in Český Brod and two in Banska Bystrica. 

The first prototype has been designed in Banska Bystrica in 1826. There have been found original plans of two buildings in archive in 1960s and afterwards have found one of them still standing. There have been released some short publication back then concearning this great discovery. However, the most publication – except for The Oxford Dictionary of Architecture :), do not recognise Schnirch as an inventor of suspended roof constructions. This one object is acctually still standing there and hundereds of people are walking by every day, not noticing. The house has been originally constructed in 15th-16th century, yet in 1826 it has got a new roof covering area of 12.4 x 25.6m. All in all, 26 chains in the distance of appx. 49.5cm are ankered in the facades and deflected over a two gothic masonry arches in the middle. Each chains is composed of 5 segments made out of crubicle steel with min. 0.8 x 2.5cm (1/3 Zoll x 1 Zoll) [6].


The axonometry shows the load bearing principle and the main construction components. These have been added to the historical substance from 15-16th century in 1826. Vertically, the tensile force from chains is anchered into the facade which is balanced by its dead load. These anchors can be seen in certain areas underneath the plaster. The horizontal share is being distributed into the walls through additional  horizontal arches built upon the ceiling. The diverting is being carried out by two gothic arches built in masonry, these have additional tiebacks from flat-steel-profiles. The ethernit tiles has replaces the original roof coat and during this reconstruction, a wooden substructe has been added as well. The original roof coat has been built out of cast-iron elements – some of them have been found on site and documented (by third party). However, there are no available measurements. Looking at the holes, where the original wires have been attached to the main chains, an appx. 14,6 cm (equals ca. 5,5 Zoll = 14,487cm) interval has been noticed. On those, Schnirch proposed to hang cast-iron elements of 55 □ Zoll in his article and a sketch presented a rectangularly shaped tiles. So we could come to e.g. 10 x 5,5 Zoll (26,4cm x 14,5cm) big tiles which were overlaping by half of the length. For more vivid image, make sure to click through the gallery attached below. I have left out the structural analysis on purpouse as this article is not supposed to be too scientific. However, if you are interested in more details please let me know so in the comment section.

All in all, I have been fascinated by the simplicity of the structure and its good condition. It has passed about 160 years, yet the chains are (except for one split piece) still intact and the roof still suits it purpose. However, I have been disappointed by the ethernit plates and their wooden substructure which declassified the lightness of the suspended roof.

[2] 1740 begins the production of crucible steel, the process has been invented by Benjamin Huntsman. However, the production in similiar ovens has started in Germany in 1823, thanks to Friedrich Krupp and his mild steel. In the mean time, Henry Cort has produced puddled steel in 1784 and England has become a leader in the business for many coming years.

[4] Calude Louis Marie Henry Navier (1785-1836) has contributed a great deal to Mechanics and Analysis through his life. In 1823, he published Rapport .. etc mémoire sur les ponts suspendus in French. It is a remarkable work regarding suspended bridge constructions and their static and dynamic behaviour, it is also responsible for the boom of suspended bridges in late 1820s. The paper has been partially translated into German in 1825 by J.F.W.Dietlein (1787-1837), Berlin. The full german version has been presented in 1829 by J.G.Kutschera in a paper Bericht an Herrn Becquen und Abhandlung über die (Ketten-)Hängebrücken von Herrn Navier. So, the only way Schnirch would based his article on the Navier’s work were if he understood French, which is possible, yet not proved. 

[5] The suspended bridge in Straznice has been erected as the first of its kind on the european land in 1823-24 and served till 1857(61). The first suspended bridge in steel has been builtby James Finley in 1801 in USA and the first in Europe came around 1817 – designed also by Finley.

Folk architecture, Cicmany.

The enchanting village Čičmany [1] is located in central western part of Slovakia enclosed by mountains Strážovské vrchy. Originally founded in 1272, the village has been declared a national monument of folk architecture in 1977 (Národná kutúrna pamiatka –  rezervácia ľudovej architektúry) due to its unique architecture, traditional clothing and embroidery. There can be found 33 listed objects  – log houses decorated with ornaments in white colour. Through the time, these patterns has developed from simple geometrical drawing into complex art and  have become a part of village´s identity, its trademark and national pride. It took me 25 years to pay this unique place a visit. I have had a good knowledge base going there as I have recently written a paper in school about it [2]. I am not going to bore you with more details. However, my obsession with folk architecture has to be elaborated further. 

I have been frequently asked the question ‘What is there to see in Slovakia?’ and as majority of my friends are foreigners, I have often played a tour guide as well. It is not an easy job to do so here. Slovakia has no pyramids, the number of expectional landmarks is very limited, neither would you find great museums here. Bratislava, the capital of Slovakia, is nothing like those other great historic cities in central Europe, e.g. Prag, Vienna or Budapest. I used to be very intimidated by this fact and have struggled for a long time what to show my friends. You have to know, Slovakia has been a part of Kingdom of Hungary, later a part of The Austria-Hungary Monarchy, and has only recently separated from Czech Republic [3]. Therefore folk traditions and local architecture were the only mean to form a national identity and the high culture has been absent for centuries. Yet, I have learned to look at things from different angle when studying architecture. I have reased, folk music and dance, traditional costumes, and vernacular architecture should be considered the greatest Slovak monument with all its intangible aspects and the best part is, they are being embraced even nowadays. 

Folk architecture is very unique and impulsive – it is never finished and constantly changing.[4] It is alive as long as there are people (folk) who maintain those traditions and it becomes extinct when the last member passes on. Unfortunatelly, folk architecture is lacking external publicity. You can read about renaissance palaces, gothic cathedrals, or english gardens – they all follow some specific set of rules, yet the folk architecture is a mystery. It works with random ideas, sometimes even very strange ones. That is the part I appreciate most about it.

However, Čičmany, its urbanism and structures themselves, is the only folk monument which was created based on plan. The majority of current urban pattern is based on master plan proposed in 1923 and most log-houses were constructed in 20th century. The reservation of folk architecture includes all in all 115 objects, 32 are listed on as heritage, yet only 3 houses have been built before 1921. Nevertheless, these objects represent a valuable documentation of original type of rural housing objects in the region, traditional building techniques and for the village characteristic decoration elements with unique emotional impressiveness.[5] Furthermore, the village is a rare example of preserving folk architecture under supervision of conservation experts, including architects and urban planners. Chosen approach to reconstruct the village as a whole unit after the destructive fires in 1907 and 1921 prove the historical and cultural significance of the place even at the beginning of 20th century. It is also one of few conservation projects in the central Europe from this period. We might not have Versailles in Slovakia but we definitely have plenty to offer as well – even some unconventional sights. 

The best part about folk architecture is, you do not need a college degree to understand it. It is quite straight forward, made by people for people, pleasing your eyes. You can check out some samples from Cicmany in the gallery attached below. It is like entering a kingdom of gingerbread houses.
