Historically, Denmark, like its Scandinavian neighbors, has been one of the most socially progressive cultures in the world. For example, in 1969, Denmark was the first country to legalise pornography, and in 2012, Denmark replaced its "registered partnership" laws, which it had been the first country to introduce in 1989, with gender-neutral marriage. Modesty, punctuality but above all equality are important aspects of the Danish way of life.
The astronomical discoveries of Tycho Brahe (1546–1601), Ludwig A. Colding's (1815–1888) neglected articulation of the principle of conservation of energy, and the brilliant contributions to atomic physics of Niels Bohr (1885–1962) indicate the range of Danish scientific achievement. The fairy tales of Hans Christian Andersen (1805–1875), the philosophical essays of Søren Kierkegaard (1813–1855), the short stories of Karen Blixen (penname Isak Dinesen), (1885–1962), the plays of Ludvig Holberg (1684–1754), the modern authors such as Herman Bang and Nobel laureate Henrik Pontoppidan and the dense, aphoristic poetry of Piet Hein (1905–1996), have earned international recognition, as have the symphonies of Carl Nielsen (1865–1931). From the mid 1990s, Danish films have attracted international attention, especially those associated with Dogme 95 like those of Lars Von Trier. Indeed, the country has always had a strong tradition of movie making and Carl Theodor Dreyer is recognised as having been one of the world's greatest film directors.
Copenhagen is home to many famous sites and attractions, including Tivoli Gardens, Amalienborg Palace (home of the Danish monarchy), Christiansborg Palace, Copenhagen Cathedral, Rosenborg Castle, Opera House, Frederik's Church (Marble Church), Thorvaldsens Museum, Rundetårn, Nyhavn and the Little Mermaid sculpture.
