The Blue Planet, a swirling vortex designed to suck you in to learn about life under the sea, opens in Copenhagen. Designed by 3XN, The Blue Planet is now Europe's largest aquarium and is devoted to education about aquatic animals as well as the important connection between water and the planet. Filled with 7 million liters of sea water, the aquarium has a variety of exhibitions to introduce the young and old to different animals and environments. Naturally, the aquarium is also dedicated to saving endangered species, improving water quality, protecting habitats and raising environmental awareness. The Blue Planet, is the newest version of the Denmark Aquarium in Copenhagen dating back to 1939. Located on the shores of (Oeresund), the aquarium has a picturesque view of the sea and convenient access to roadways and the city. Design of the project began back in 2007 through an international competition, which local firm 3XN won with their swirling proposal. Construction was completed in 2013 with an official opening date of March 22nd of 2013. The design is meant to draw you in, like a whirling vortex and pull visitors down into the depths of the water to explore and learn about life under the sea. Kim Herforth Nielsen, Creative Director and Principal at 3XN, who is the architect of the building explained, "Our wish was to bring our visitors all the way down to the world of the fish. Therefore, the design of The Blue Planet is based on the story about water and life under the sea. We visualize the construction as a whirlpool which draws visitors into the depths to the fascinating experiences waiting among fish and sea animals from all over the world." Upon entrance into the center of the vortex, the public can choose one of four whirls, each with different exhibitions including the coral reefs, the ocean, Africa's lakes, the Amazon river, the Faro bird cliffs and even an exhibit about the ocean right outside the aquarium. The Blue Planet is home to 450 different species and 20,000 fish and other aquatic animals, which include sharks, sea lions, dwarf crocodiles, moray eels, barracudas and much more. Water inside the aquarium is filtered and recycled in a closed loop system, while seawater is used to keep the entire facility cool. One of the whirls with indoor gardens and vegetation is naturally lit from above with skylights. The Blue Planet is devoted to nature conservation as well as raising awareness to water issues. The aquarium partners with researchers for scientific collaboration and work to reduce over-fishing, pollution and endangered species. It was also designed to be sustainable and self-sufficient as part of their mission to further and promote solutions that benefit the environment and nature.

Thierry Henry has lodged controversial plans to demolish his US$ 9.5 million north London house and replace it with a larger property - incorporating a 12 meters high fish tank that will cost US$ 400 thousand to build, reported The Daily Mail. Henry wants to rebuild his luxury home - which was completed only in 1999 and is described as one of the finest examples of modern architecture in the UK. Stretching 12 meters from the bottom of his house to the very top, it will take 5.5 thousand gallons of water to fill house 300 fish. The aquarium will actually be made up of four separate tanks, one for each storey of the house. Each will be made of Perspex-like material and will give the optical illusion of one giant aquarium - but will be cheaper to clean, run and maintain than a single tank. Each aquarium will require a filtration system to ensure the water stays clean and fresh. Experts say there are 2 thousand species of marine life suitable for the tanks, ranging from smaller breeds of shark to clown fish, yellow tangs, blue tangs and angel fish. Henry's new home will be taller than the existing one and include a bar, a cinema and a swimming pool. Despite spending at least US$ 3.2 million on rebuild costs, the finished house is likely to be worth at least US$ 16 million. The footballer is keen to highlight the eco-features of the new home, which includes extensive glass paneling to capture natural light and a so-called "biodiverse" roof, which will incorporate plants and trees. The French footballer is the latest in a long line of celebrities including Madonna, the Beckhams, Cher and Premier League footballers Stephen Ireland, Joe Hart and Micah Richards, to splash out on opulent fish tanks. Ireland has reportedly spent more than US$ 160 thousand on his 4 meters aquarium, and is now believed to be planning a shark tank under his kitchen floor. But Henry's super-size version will dwarf them all.

This wonderful aquarium built at the end of 2003 in Berlin, in the atrium of "Radisson SAS Hotel" around transparent, panoramic elevator. This is made possible through the combined efforts of designers and builders of "International Concept Management, Inc.", who did design and common construction work and "Reynolds Polymer Technology", who realized the more complicated part of the project - cylindrical acrylic glass aquarium with 11m diameter and 25m height. Inner tube of the aquarium, where the elevator move, was manufactured and installed in a single piece and outdoor roller tank was collected on the site from the separate 4 pieces. The AquaDom built on a 9 meters tall concrete foundation which can bear a load of 900 000 liters of see water. A pair of divers undertakes daily cleaning and fish feeding activities for 2600 fishes of 56 different species. This gigantic aquarium is the largest acrylic glass cylinder in the world and one of the most visited sights of Berlin.
