Sagrada Familia Sagrada Família is a large Roman Catholic church in Barcelona, Catalonia, Spain, designed by Catalan architect Antoni Gaudí (1852 -1926). Although incomplete, the church is a UNESCO World Heritage Site, and in November 2010 was consecrated and proclaimed a minor basilica by Pope Benedict XVI. Though construction of Sagrada Família had commenced in 1882, Gaudí became involved in 1883, taking over the project and transforming it with his architectural and engineering style -combining Gothic and curvilinear Art Nouveau forms. Gaudí devoted his last years to the project, and at the time of his death in 1926, less than a quarter of the project was complete. Its construction progressed slowly, as it relied on private donations and was interrupted by the Spanish Civil War - only to resume intermittent progress in the 1950s. Construction passed the midpoint in 2010 with some of the project's greatest challenges remaining and an anticipated completion date of 2026 - the centennial of Gaudí's death. The basílica has a long history of dividing the citizens of Barcelona - over the initial possibility it might compete with Barcelona's cathedral, over Gaudí's design itself, over the possibility that work after Gaudí's death disregarded his design, and the recent possibility that an underground tunnel of Spain's high-speed train could disturb its stability.

Tower bridge Tower Bridge (built 1886–1894) is a combined bascule and suspension bridge in London, over the River Thames. It is close to the Tower of London, from which it takes its name. It has become an iconic symbol of London. The bridge consists of two towers tied together at the upper level by means of two horizontal walkways, designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers. The bascule pivots and operating machinery are housed in the base of each tower. The bridge's present colour scheme dates from 1977, when it was painted red, white and blue for the Queen Elizabeth II's silver jubilee. Originally it was painted a mid greenish-blue colour. Tower Bridge is sometimes mistakenly referred to as London Bridge, which is the next bridge upstream.

The Moscow Kremlin, sometimes referred to as simply the Kremlin, is a historic fortified complex at the heart of Moscow, overlooking the Moskva River (to the South), Saint Basil's Cathedral and Red Square (to the East) and the Alexander Garden (to the West). It is the best known of kremlins (Russian citadels) and includes four palaces, four cathedrals and the enclosing Kremlin Wall with Kremlin towers. The complex serves as the official residence of the President of the Russian Federation. The name the Kremlin is often used as a metonym to refer to the government of the Soviet Union (1922–1991) and its highest members (such as general secretaries, premiers, presidents, ministers, and commissars), in the same way that the metonym Élysée Palace refers to the President of the French Republic, the White House refers to the Executive Office of the President of the United States and Number 10 Downing Street or Whitehall refers to the Offices of Prime Minister of the United Kingdom and the British Government. It is still used in reference to the government of the Russian Federation and even the Russian President's official website is Kremlin.ru. "Kremlinology" refers to the study of Soviet and Russian policies. Moscow Kremlin
