Architecture firm Snøhetta has revealed plans to build a restaurant in southern Norway that will be partly submerged in the sea to give diners a glimpse below the waves, reported The Dezeen. Described by the Oslo- and New York-based firm as "Europe's first underwater restaurant", the building will comprise a rugged concrete box with half of its body on the coastline, and the other half sunken underwater. Its primary use will be as a restaurant for up to 100 people, but it will also function as a marine research center and as an artificial mussel reef. Once inside, visitors will be able to look through a huge panoramic window to observe sea life at first hand. The building will be called Under – a word that the architects say is very similar to "wonder", when translated into Norwegian. It will be built near the village of Båly in Norway's Lindesnes region, on the country's southernmost tip. The building's concrete walls will be a meter thick, helping to withstand its inhospitable environment. Externally, this concrete will have a coarse texture, to encourage mussels to attach themselves to the structure. Meanwhile, the marine research center inside will facilitate studies into fish behavior – specifically whether it is possible to train wild fish with sound signals, and also whether fish act differently in different seasons. A huge frame-like oak wall will provide the building's entrance, which will lead through to a wood-lined restaurant space. The dining room will be painted in deep blue and green hues "inspired by the seabed, seaweed and rough sea". There will also be a champagne bar, featuring more subdued tones, intended to evoke shells, rocks and sand. The large panoramic window, measuring 11 meters wide, spans the entire end wall of the space.

A nearly 500 meters bridge for hikers built as the longest hanging pedestrian bridge in the world opened near the Swiss town of Zermatt. The 494 meters long and 65 centimeters wide bridge named the Europe Bridge, hangs up to 85 meters above Grabengufer ravine. It replaces a previous bridge that had been damaged by rock falls. The Zermatt Tourist Board says it is the world’s longest, although a 405 meter bridge in Reutte in Austria hangs 110 meters higher above the ground. Built by local company swissrope/Lauber Seilbahnen during 10 weeks, the bridge completes a section of the Europaweg trail, a high-altitude walking route offering panoramas of some of Switzerland’s highest peaks, including the Dom (4,545m) and the Matterhorn. The new bridge, whose cables weigh about eight tones, is equipped with a system to prevent it from swinging, the Zermatt Tourist Board said.
