Corten Footbridges Serve as a Roof for the Helfštýn Castle Palace, Czech Republic | Atelier-r

Atelier-r, Olomouc, Czech Republic based architecture studio has recently finished the renovation and restoration work of the Helfštýn Castle, which is the second-largest complex in the Czech Republic right after Prague Castle. The castle was closed in 2014 due to the serious risk of collapse of portions of walls. But now it has reopened with some renovation. To preserve the castle’s authentic character, the architecture firm inserted flat glass roofs between the walls of the ruins that work as a sightseeing route for the visitors to enjoy the picturesque views from the footbridges on the top levels of the castle. SURFACES REPORTER (SR) brings all information about the new additions in the castle. Také a look:

Rising high above the Moravian Gate valley, this castle was established in the 14th century. In 2014 the Renaissance palace ruins had to close down due to severe safety hazards such as falling masonry and remains degradation.

The primary requirement of the castle owner; Olomouc Region, was to renovate the palace along with the construction of a new roof. The National Heritage Institute insisted on the preservation of the building in the state of ruin. The roof was allowed only partially, and it could only go as high as the level of the peripheral walls.

The project planning was rather unique. The 3D model based on thousands of photographs from a drone allowed us to map all the types of plaster and masonry modifications

New Concept

The studio aspired to go beyond the technical reconstruction assignment.

 It strived to complement the historical building with the contemporary architecture that would focus on both practical use as well as gaining an aesthetic appeal. 

Flat Glass Roof

In order to immerse the visitors in the historical development of the original renaissance palace we inserted new sightseeing routes into the already existing gaps in the ruins, connecting the ground floor with the newly accessible higher levels of the palace.

Newly added contemporary elements are clearly recognizable in the historical construction.

The firm worked with three basic materials, one for each level of the building. The roofing is made of glass on steel beams, the staircases and footbridges have been made of corten steel and the ground floor paths are made of polished concrete.

The flat glass roofs have been inserted in between the walls of the ruins. The wide-open sky was the key inspiration when choosing the material for the roof. Using glass provides perfect day light conditions to the interior of the palace.

The firm has chosen to work with the sanded glass for a couple of reasons. It is easy on the maintenance and the flat dispersed light compliments the exhibitions inside the palace. The chapel roof was an exception. The clear glass roof symbolizes heaven quite literally.

The architect has also put a roof on five chosen chambers only.

The corten footbridges serve as a roof for the staircases.

The firm intentionally left out some of the spaces in order to enhance the spirit of the impressive ruins and encourage the visitors to look up to the sky.

What once used to be a roof has now become the new sightseeing route.

Being this close to the construction details of the original palace and as high as the top of the walls allows the public to admire the historical significance of the sight and the sheer views of the surrounding region.

Flat Glass Roof

It was crucial to choose a material that would be timeless.

Corten is a special iron alloy that undergoes a corrosion, matures and matches the texture of the old historical walls.

Moreover, Helfštýn Castle is well-renowned for its iron craftsmanship tradition, therefore it made a perfect sense to choose corten to work with. 

Concrete Paths

On the ground floor the firm designed a network of marching areas and pavements from precise smooth pre-cast concrete boards laid down into individual areas.

Flat Glass Roof

Pre-cast concrete is defined by rigorously straight Corten steel profiles that create a distance from uneven and irregular walls.

The area between precise profile and irregular walls is dumped by gravel that highlights both and conciliates irregularity with uncompromising straight forefront.

Flat Glass Roof

Past and Present

The concept is based on the respect towards the historical building and it pursues a major effort to preserve the castle’s authentic character.

Flat Glass Roof

The palace gained an attractive sightseeing route that allows the visitors to learn about the building history and enjoy the picturesque views from the footbridges on the upper levels of the castle what once used to be a roof.

Flat Glass Roof

The contemporary architecture does not compete with the historical building, rather it creates a cohesive unit in which all the elements, old and new go hand in hand.
