The Allianz Arena stadium was built in 2002-2005 for the World Cup 2006 that was held in Germany. Construction cost is around 550 million euros. The stadium is the home arena of the best German football club Bayern (Munich).
The facade and roof are made up of 2,760 pillows that are inflated with dry air pressure. The material from which the pillows are made is 0.2 mm thick. Each pillow can be individually illuminated in red, blue and white colors and their shades. When Bavaria plays here, the stadium is red, and if the national team plays, then white. The cost of electricity is approximately €50 per hour.
During the World Cup a huge sponsor inscription "Allianz" was removed from the front, and it was called "FIFA World Cup Stadium in Munich." Six matches, including a semi-final, were played there.
You can see the interiors of the stadium during a tour. Every day at 1 am (except the days of matches) tours in English start. All relevant information is here. You can also purchase tickets online.
