Switzerland produced architectural movements that altered how the world builds. Le Corbusier, born Charles-Édouard Jeanneret in La Chaux-de-Fonds in 1887, published "Vers une Architecture" in 1923, establishing five points of modern architecture that became foundational to twentieth-century building practice. His Villa Savoye in France applied principles he developed while working in Switzerland, but his Swiss buildings demonstrate the evolution of his thought. The Immeuble Clarté in Geneva, completed in 1932, used steel frame construction with glass curtain walls, implementing industrial building methods in residential architecture. The Pavillon Le Corbusier in Zurich, finished in 1967 as his final building, employed modular steel and enamel panels in a system he called "Boisec," creating a structure that floats above Lake Zurich on pilotis. His Petite Maison in Corseaux, built in 1924 for his parents, measures 60 square meters and demonstrates his concept of the "minimum dwelling" with precise spatial efficiency.
The Benedictine Convent of St. John at Müstair, a UNESCO World Heritage site since 1983, contains Carolingian frescoes from approximately 800 CE that cover 150 square meters of wall surface. These paintings depict scenes from the life of Christ in a narrative sequence that represents one of the most complete surviving Carolingian fresco cycles in Europe. The convent itself dates to the late eighth century, founded according to tradition by Charlemagne around 775 CE. The Romanesque bell tower added in the tenth century stands 30 meters high. Restoration work in the 1940s and 1950s removed baroque plaster to reveal these medieval paintings underneath, with conservators discovering five distinct layers of paint applied between the eighth and twelfth centuries. The chapel's architectural plan follows a three-apse design typical of Carolingian ecclesiastical building in the Alps.
The Grossmünster in Zurich, where Huldrych Zwingli preached from 1519 to 1531, shaped Protestant church architecture by removing decorative elements. Zwingli ordered the removal of all images, reliquaries, and the organ in 1524, creating an austere space focused on preaching rather than sacramental ritual. The Romanesque church's twin towers, rebuilt in the 1780s after fire damage, reach 64 meters in height. The building's original construction began around 1100 CE, with the nave completed by 1150 and the choir by 1220. The crypt contains capitals carved around 1100 showing Daniel in the lions' den and other Old Testament scenes. Sigmar Polke installed stained glass windows in the north transept in 2009, using agate slices that create abstract light patterns, marking the first major decorative addition to the church interior in nearly five centuries. Augusto Giacometti, grandfather of sculptor Alberto Giacometti, created the nave's stained glass windows in 1932, using geometric abstraction rather than figurative imagery.
The Fraumünster in Zurich contains five choir windows created by Marc Chagall in 1970 and a rose window he completed in 1978. The choir windows measure 10 meters high and depict biblical themes: Prophets (in blue), Jacob (in blue and green), Christ (in yellow and green), Zion (in green), and the Law (in red). Chagall was 83 years old when he finished these windows, working in collaboration with the Zurich glassmaker Stocker. The church itself dates to 853 CE, founded as a convent by Louis the German for his daughter Hildegard. The Romanesque choir and transept date to approximately 1250, while the Gothic nave was completed around 1300. Giacometti also created windows for this church in 1945, installed in the north transept. The building's Gothic spire, added in 1732, rises 54 meters.
The Basel Minster, constructed between 1019 and 1500 CE, employed red Vosges sandstone that gives the building its distinctive color. The Romanesque structure was damaged in the 1356 Basel earthquake, which measured approximately 6.5 on the Richter scale and remains the most destructive earthquake in Central European recorded history. Reconstruction in the Gothic style began immediately, with the choir completed by 1363 and the towers finished in 1500. The north tower called the Georgsturm stands 64.2 meters high, while the south tower, the Martinsturm, reaches 62.7 meters. The church contains the tomb of Erasmus of Rotterdam, who died in Basel in 1536. The Reformation reached Basel in 1529, and the Minster became Protestant, with iconoclasts removing most statuary and decorative elements during three days in February 1529. The Galluspforte, the north portal dating to approximately 1180, retained its Romanesque sculptural program showing the apostles and Christ in Judgment.
The Rhaetian Railway's Albula and Bernina lines, designated UNESCO World Heritage in 2008, demonstrate early twentieth-century civil engineering in mountainous terrain. The Albula line, opened in 1904, includes 42 tunnels and covered galleries totaling 16 kilometers over a route length of 67 kilometers. The Landwasser Viaduct, completed in 1902, spans 136 meters at a height of 65 meters with six arched limestone spans before entering a tunnel directly in the mountainside. The Bernina line, opened in 1910, reaches 2253 meters at Ospizio Bernina, making it the highest railway crossing of the Alps without using a tunnel at the summit. The railway uses adhesion rather than rack-and-pinion technology, with a maximum grade of 7 percent. The spiral viaducts at Brusio, completed in 1908, describe a complete circular curve with nine arched spans totaling 143 meters in length.
La Chaux-de-Fonds and Le Locle, designated UNESCO World Heritage sites in 2009, developed urban planning designed for watchmaking. After a fire destroyed La Chaux-de-Fonds in 1794, the city was rebuilt on a grid pattern with streets running east-west to maximize natural light entering workshops. Buildings were constructed with large windows on upper floors where watchmakers worked. The city plan, designed by Charles-Henri Junod, set building heights and street widths to optimize sunlight throughout the year. Le Locle developed similarly after its 1833 fire, with architect Jean-Jacques Huguenin creating a plan that integrated residential and workshop spaces. By 1900, La Chaux-de-Fonds had a population of 36,000 and produced approximately one-third of Switzerland's watch exports. The International Watchmaking Museum in La Chaux-de-Fonds, opened in 1902, occupies a building designed by architects Robert and Charles-Edouard Jeanneret (Le Corbusier's father and brother). The museum's collection includes 4,500 timepieces and automated music boxes that demonstrate the mechanical skills developed in these cities.
Paul Klee, born in Münchenbuchsee near Bern in 1879, produced 9,000 works during his career. The Zentrum Paul Klee in Bern, designed by Renzo Piano and opened in 2005, holds 4,000 of these works, representing 40 percent of his total output. The building's three earth-covered waves, made of steel and glass, span 150 meters in length with the central wave reaching 19 meters in height. Klee taught at the Bauhaus from 1921 to 1931, developing color theory based on his understanding of music and his experience as a violinist. His "Pedagogical Sketchbook," published in 1925 as a Bauhaus book, analyzes pictorial elements using arrows, vectors, and geometric forms. When the Nazis declared his work "degenerate art" in 1933, Klee returned to Bern, where he died in 1940. His late works, created while suffering from scleroderma, employ thick black lines and simplified forms. "Death and Fire" from 1940 shows a face made from the German word "Tod" (death), painted months before his death.
Alberto Giacometti, born in Borgonovo near Stampa in 1901, created bronze figures whose elongated proportions altered modern sculpture. His father, Giovanni Giacometti, was a post-impressionist painter; his godfather, Cuno Amiet, was a founding member of Die Brücke.
