The Sagrada Familia church in Barcelona, Spain, has been under construction for more than 130 years, but now thanks to the 21st century technology of 3D printing, the 19th century project may finally be completed by 2026. This is perhaps one of the longest active construction projects on the planet. Construction work began in 1882, but only a quarter of the church was completed at the time of his death in 1926. Although there is still much work left to be done to complete Gaudi's vision, the church is already structurally sound, open to the public, and completely stunning, reported BBC. In part because of its long lifespan, this project has captivated architects and designers since its inception. What delights folks now is the amazing progress that 3D printing has enabled the present-day architecture team to stay as true as possible to the intent of the design's original creator. Project leaders began using 3D printing in 2001, but the technology has advanced so much in recent years that it is now more useful and accurate than ever. Chief architect Jordi Coll believes that Gaudi himself would have been a great proponent of 3D-printed architecture. "Due to the complexity of surfaces and forms, working with Gaudi's designs in 2D does not make sense from an architectural point of view," he said, as quoted by 3D Systems. "If Gaudi was alive today, he would have brought 3D technology to its maximum exponent, since much of his work was already conceived tri-dimensionally." Due to the scale of the project, Sagrada Familia has its own technical studio which acquired two 3D printers to help with the construction. The printers are being used, in large part, to reconstruct 3D models of the building, following Gaudi's designs. The original plaster models created from Gaudi's 2D drawings were almost completely destroyed by vandals during the Spanish Civil War, along with most of his writings and photographs. Architects are working hard to use modern technology to piece back together Gaudi's design, and the progress they've made on the building has most visitors feeling like they must be doing a good job.

Today approximately there are 41 Eiffel Tower replicas over the world, 3 of which are situated in China. Forth one, a half size replica of the Eiffel Tower also will be opened in 2016 in Macao, China. But this is not the end. Dozens of this brand tower, of course, will be built in the future. Last year Asia Sands China Ltd., a subsidiary of Las Vegas Sands, has received approval from the Macau government to build a US$ 2.7 billion Paris-themed resort in the Portuguese colony. Recently Edward Tracy, President and Chief Executive Officer of Sands China announced that the construction of the 3,000-room hotel The Parisian Macao is in full swing. The French-themed Parisian Macao will have more than 3,000 rooms, 45 thousand square meters of retail space, five-star public spaces, authentic French restaurants and a half-scale Eiffel Tower, with an observation deck and a restaurant on the third floor. Guests and visitors will be able to take an elevator to the top of the tower, which will have a panoramic view of the city and the Pearl River Delta. It will be a fully integrated resort with a variety of scenic locations. The Parisian Macao will have fashion-forward retail offerings and outlets focused on jewelry, watches, and fashion accessories. All of its facilities will be interconnected by climate-controlled, air-conditioned bridges with moving walkways, thus allowing tourists to experience offerings without exposing themselves to traffic or weather.

A 74-room mansion used by Napoleon Bonaparte as his headquarters during a famous battle has been put up for sale, reported Daily Mail. It is on the market at US$ 5.78 million with Beauchamp Estates, which also has a two-bedroom flat for sale at a similar price in London's Belgravia. Villa La Voglina in Piedmont, Italy, was built in the 18th century by the world-renowned Baroque architect Filippo Juvarra. The historic property is set in 240 thousand square meters and boasts 13 bedrooms, 9 bathrooms and a private chapel with seating for 30 people. The property also has 2 dining rooms, 2 kitchens, 10 reception rooms and a guest house. There are beautiful formal gardens and terraces along with a vineyard which, if restored, could produce around 100 thousand bottles of wine per year. Some 215 years ago, the French emperor used Villa La Voglina as his headquarters for the Battle of Marengo. The fighting between the French and Austrians took place near the city of Alessandria in Piemonte on June 14, 1800.

Museum-institute after Komitas opened its doors in Yerevan as part of Armenian Genocide 100th anniversary. The museum consists of several rooms - concert hall, research center, music studio, library, publishing house and 8 halls where a huge intellectual heritage of the Master is presented. First proposal about the museum construction was made on May 30, 2013 during a meeting of Trustees' Board of All-Armenian Fund Hayastan. Fund decided to convey to Armenian Government former Cultural Palace in the park after Komitas. But this building was partially dilapidated. The project was funded by "Phoenix" fund philanthropist Gabriel Jambarjyan. Museum construction started on September 19, 2013. Project architect is Arthur Meschyan. During the museum inauguration architect said, in this case the building architecture wasn't important. The architecture, of course, has its place, but the museum is the people, not the building.

A 5000 year- old underground city thought to be the largest in the world has been discovered in central Turkey. The subterranean settlement was discovered in the Nevsehir province of Turkey's Central Anatolia region, in the historical area of Cappadocia. Cappadocia is famous in archaeological circles for its large number of underground settlement. This area rich in history from the Hittite times before 1,700 B.C. and was once a part of the Roman Empire. The city, found in the province of Nevsehir, was discovered while developers were excavating for a new housing development in the area known in archeological circles for the amount of underground settlements. The project has since been cancelled. Despite the fact that nearly US$ 38.6 million have been spent on the housing development, the Turkey Housing Development Administration (TOKI) doesn't feel it is a loss. The underground city was found in the 45 hectares of the total 75 hectare area. Tunnel passages of 7 kilometers are also discussed. Project started in 2012. The underground city was discovered when the company began the destruction in line with the protocol. The first galleries were spotted in 2013. Escape galleries and churches were found in the underground city and the site has now been registered officially with the Turkey's Cultural and Natural Heritage Preservation Board, officials said. It is not the first underground city to be found in the Nevsehir area, but it is the most massive.
