Vienna lies in the east of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3 million inhabitants, and this region is referred to as Twin City. In 2001, the city centre was designated a UNESCO World Heritage Site.
In a 2005 study of 127 world cities, the Economist Intelligence Unit ranked the city first (in a tie with Vancouver, Canada) for quality of life. This assessment was mirrored by the Mercer Survey in 2009 and 2010. Analytically, the city was ranked 1st globally for a culture of innovation in 2007 and 2008, and 2nd globally after Boston in 2009 from 256 cities on an analysis of 162 indicators in the Innovation Cities Index on a 3-factor score covering culture, infrastructure and markets. As a city, Vienna regularly hosts urban planning conferences and is often used as a case study by urban planners. This city rates highly in popular opinion-based journalistic rankings from magazines such as the Economist Intelligence Unit, whom rated it the second best city in which to live according to their Global Livability Survey in 2011 as well as Monocle, where it is rated 8th among the "Top 25 Livable Cities" in 2010.
St. Michael's Church (German: Michaelerkirche), dedicated to the Archangel Michael, is one of the oldest churches in Vienna, Austria, and also one of its few remaining Romanesque buildings. Over time, there have been many alterations, resulting in its present day aspect, unchanged since 1792. This church, close to the Michaeler wing of the Hofburg, used to be the parish church of the Imperial Court (it was then called Zum heiligen Michael).
Over its long history, spanning more than eight centuries, this church has incorporated a medley of architectonic styles. The church is a late Romanesque, early Gothic building dating from about 1220-1240. There is a document giving 1221 as the foundation date of the church, but this is most probably a 14th century forgery.
