The Piedmont-Triad (or simply the Triad) is a north-central region of the U.S. state of North Carolina that consists of the area within and surrounding the three major cities of Greensboro, Winston-Salem, and High Point.
 This close group or "triad" of cities lies in the Piedmont geographical region of the United States and forms the basis of the Greensboro-Winston-Salem-High Point CSA.
 The area of the triad is approximately 5,954 square miles.
 The metropolitan area is connected by Interstates 40, 85, 73, and 74 and is served by the Piedmont Triad International Airport.
 Long known as one of the primary manufacturing and transportation hubs of the southeastern United States, the Triad is also an important educational and cultural region and occupies a prominent place in the history of the American Civil Rights Movement.
 The Triad is not to be confused with the "Triangle" region (Raleigh-Durham-Chapel Hill), directly to the east.
 As of 2012, the Piedmont Triad has an estimated population of 1,611,243 making it the 33rd largest CSA metropolitan area in the United States.
Smith Square is a square in the Westminster district of London, just south of the Palace of Westminster.
 The centre of the square is occupied by St John's, Smith Square, a Baroque church now used as a concert hall.
 Most of the square is now taken up by offices and the location means that they are mostly occupied by organisations associated with the government, or that need to be near it for lobbying purposes.
 In the mid 20th century the square hosted the headquarters of both the main parties of British politics, and it is now home to the Department for Environment, Food and Rural Affairs, the Local Government Association and the London base of the European Parliament and European Commission.
Church of St. Casimir (Lithuanian: "Šv.
 Kazimiero bažnyčia" , Polish: "Kościół Św.
 Kazimierza" ) is a Roman Catholic church in Vilnius' Old Town, close to the Vilnius' Town Hall.
 It is the first and the oldest baroque church in Vilnius, built in 1618.
[1] The construction of the church began in 1604 in memory of the holy prince Saint Casimir: it was built by the Jesuits with funding by the Great Chancellor of the Grand Duchy of Lithuania Lew Sapieha.
 It is traditionally assumed that the corner stone (which can be seen on the façade wall) was pulled into the city by procession of 700 Vilniusites from the Antakalnis hills.
 The construction was finished in 1616, and the interior design completed in 1618.
 The Church of St. Casimir is one of the earliest exemplary Baroque buildings in the city, designed along the line of the famous Il Gesù church in Rome (Church of the Gesù).
 It was apparently designed by Povilas Bokša, and the construction was supervised by Jan Frankiewicz, a pupil of architect Giovanni Maria Bernardoni.
 In the middle of the 18th century the church was reconstructed by architect Tomas Žebrauskas.
 Under his supervision a stepped lantern cupola with a crown was erected.
 This large and impressive cupola is unique in the entire region of the former Grand Duchy of Lithuania.
 Under Russia's occupation the church of St. Casimir was converted into a Russian Orthodox church.
 In 1915 Vilnius was occupied by the Germans and the church was converted into the Evangelical Lutheran prayer house of the Vilnius Garrison.
 In 1919 the church of St. Casimir was returned to the Catholics, but was damaged again during the Second World War, closed down and in 1963 converted into a Museum of Atheism.
 The church was reconsecrated in 1991.

 It is located in the immediate proximity of Am Hof square, Schulhof, and Wipplingerstraße.
 It exemplifies the long and eventful history of the city and the Jewish community focused on this place.
 Archaeological excavations of the medieval synagogue are viewable underground by way of the museum on the square, Misrachi-Haus.
 Two sculptural works, a carved relief and several inscribed texts are located around the square that all have subject matter relating to Jewish history.
 One of these sculptures is a statue of Gotthold Ephraim Lessing.
 The other is a memorial to Austrian Holocaust Victims, a project based on an idea of Simon Wiesenthal and unveiled in 2000.
 Created by British artist Rachel Whiteread, the memorial is a reinforced concrete cube resembling a library with its volumes turned inside out.
 The Judenplatz is the location of the Constitutional Court of Austria and the Administrative Court of Austria.
