Zhangye Danxia Landform - China

The Danxia landform refers to various landscapes found in southeast and southwest China that "consist of a red bed characterized by steep cliffs". It is a unique type of petrographic geomorphology found in China. Danxialandform is formed from red-coloured sandstones and conglomerates of largely Cretaceous age. The landforms look very much like karsttopography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called "pseudo-karst" landforms.

The first studies were conducted on what are now referred to as Danxia landforms were conducted at Mt. Danxiashan, located near Shaoguan, China. In the 20s and 30s Chinese geologists made an effort to learn more about these interesting geomorphic structures.Similar in looks to karst topography, danxia landforms are made up uplifted continental crust that has been faulted and eroded, exposing large scarps of layered rock, red in color.

Plitvice Lakes National Park - Croatia

Plitvice Lakes National Park  is the oldest national park in Southeast Europe and the largest national park in Croatia.

The protected area extends over 296.85 square kilometres (73,350 acres). About 90% of this area are part of Lika-Senj County, while the remaining 10% are part of Karlovac County.

In 1979, Plitvice Lakes National Park was added to the UNESCO World Heritage register among the first natural sites worldwide. Each year, more than 1,200,000 visitors are recorded. Entrance is subject to variable charges, up to 110 kuna or around $18USD per adult in peak season.

The national park is world famous for its lakes arranged in cascades. Currently, 16 lakes can be seen from the surface.These lakes are a result of the confluence of several small rivers and subterranean karst rivers. The lakes are all interconnected and follow the water flow. They are separated by natural dams of travertine, which is deposited by the action of moss, algae, and bacteria. The particularly sensitive travertine barriers are the result of an interplay between water, air and plants. The encrusted plants and bacteria accumulate on top of each other, forming travertine barriers which grow.

Raiffeisen Skywalk - Switzerland

The entrance to the new foot suspension bridge "Raiffeisen Skywalk" is right beside the Stuckli Rondo gondola station on Mostelberg. This bridge hangs high above the wild and romantic Lauitobel valley at a height of up to 58 metres! At a length of 374 meters, it is currently the longest foot suspension bridge in Europe. 

The suspension bridge may be used in both winter and summer and is open during operating hours of the Sattel-Hochstuckli lifts. Outside of these opening hours, entrance to the bridge is blocked. The walkway is between 90 and 180 cm wide, so guests in wheelchairs and families with strollers can also enjoy this unique experience. 

The bridge is monitored by video camera, while wind- and level meters help ensure the highest standard of safety. The structure is attached by four 50 mm thick cables and secured to the ground with 20 metre long ground anchors. Each individual cable has a load-bearing capacity of 250 tonnes. The walkway is made of a grating which is safely accessible both in rain and snow and also allows for snow removal.

Palais idéal - France

Cheval, a French postman, started to build the building in April 1879. He claimed to have stumbled on a rock and have been inspired by the shape of it. Returned to the same spot the next day and started collecting stones. 

For the next 33 years, during his daily routine Postman Cheval carried stones he found on the road and at home used them to build the Palais idéal. Initially, carried the stones in his pockets, then a basket and eventually a wheelbarrow. He often gathered stones at night, the light of an oil lamp. 

Cheval spent the first two decades building the outer walls. The Palace is a mix of different styles with inspirations from the Bible to Hindu mythology. Cheval bound the stones with wire, lime and cement.
