Memorial to the victims of the Shoah

Trinity Church (Luxembourgish: Dräifaltegkeetskierch; French: Église de la Trinité; German: Dreifaltigkeitskirche), also known as the Protestant Church, has been used since 1817 for Protestant services in the city of Luxembourg. It is located on Rue de la Congrégation in the old town.

Notre-Dame Cathedral (Luxembourgish: Kathedral Notre-Dame, French: Cathédrale Notre-Dame, German: Kathedrale unserer lieben Frau) is the Roman Catholic Cathedral of Luxembourg City, in southern Luxembourg. It was originally a Jesuit church, and its cornerstone was laid in 1613. It is the only cathedral in Luxembourg. The church is a noteworthy example of late gothic architecture; however, it also has many Renaissance elements and adornments. At the end of the 18th century, the church received the miraculous image of Our Lady of Consolation (Latin: Sancta Maria Consolatricis Afflictorum), the patron saint of both the city and the nation. Fifty years later, the church was consecrated as the Church of Our Lady and in 1870, it was elevated by Pope Pius IX to the Cathedral of Notre-Dame. At the cemetery of the cathedral is the National Monument to the Resistance and to the Deportation. The centerpiece of the monument is the famous bronze monument by the 20th century Luxembourgish sculptor Lucien Wercollier called The Political Prisoner. The high altar of the cathedral enshrines an image of the Blessed Virgin Mary under the nationally venerated title of Our Lady of Consolation. The cathedral was expanded and enlarged from 1935 to 1938.

The Catholic Archdiocese of Luxembourg (Latin: Archidioecesis Luxemburgensis) is an archdiocese of the Latin Church of the Catholic Church in the Grand Duchy of Luxembourg, comprising the entire Grand Duchy. The diocese was founded in 1870, and it became an archdiocese in 1988. The seat of the archdiocese is the Cathedral of Notre Dame in the city of Luxembourg, and since 2011 the archbishop is Jean-Claude Hollerich.

The Codex Mariendalenis is a manuscript on vellum containing the epic poem Yolanda vu Veianen or Yolanda of Vianden. It is believed to be the work of Brother Hermann von Veldenz who probably wrote the story of Yolanda's life in 1290 after her death in 1283. The work consists of 5,963 lines of rhyming couplets in Moselle Franconian which bears close similarities to today's Luxembourgish. It is therefore of particular interest to those tracing the history of the Luxembourgish language.

The René Konen Tunnel (French: Tunnel René Konen), colloquially known as the Saint Esprit Tunnel (French: Tunnel du St-Esprit, Luxembourgish: Helleg-Geescht-Tunnel), is a 655 m (2,149 ft) road tunnel in Luxembourg City in southern Luxembourg. It carries two lanes of one-way traffic northwards, under Ville Haute, bypassing the narrow streets and pedestrian zone in the heart of the city. At the southern end (49°36′29″N 6°07′59″E), the tunnel is fed by the Passerelle, which carries traffic from Gare, on the southern side of the Pétrusse valley. The tunnel's entrance is under the Judiciary City. At 100 metres (330 ft), the tunnel bears to its right, passes under the Chambre des Députés (49°36′38″N 6°07′59″E) and heads back to the left in a long, sweeping bend. At its northern end (49°36′49″N 6°07′55″E), the tunnel emerges just to the west of the Alzette valley. The road onto which it leads then divides into two, feeding the Boulevard Royal to the west and the Côte d'Eich to the north. On November 5, 1998, it was officially named after René Konen, a member of the Democratic Party, who served from 1979 until 1984 as Minister for Public Works in the Pierre Werner cabinet, and who initiated the tunnel's construction.

Krautmaart (Luxembourgish) or rue du Marché aux Herbes (French), is an irregularly-shaped street in Luxembourg City, in southern Luxembourg. The street, whose name translates into English as Herb Market street, is situated in Ville Haute, the historic heart of the city. It lies to the east of Place Guillaume II, across the rue du Fossé. Due to the presence of the seat of Luxembourg's Chamber of Deputies on the street, 'Krautmaart' is used as a metonym for the Luxembourgish legislature. Despite this, it is the adjoining Grand Ducal Palace that dominates Krautmaart.

Luxembourg City Hall (Luxembourgish: Stadhaus Stad Lëtzebuerg; French: Hôtel de ville de Luxembourg) is the city hall of Luxembourg City, in southern Luxembourg. The city hall is the centre of local government, including being used as the private office of the Mayor of Luxembourg City. Because of its position in Luxembourg's capital, it regularly hosts foreign dignitaries. It is located on the southwestern part of Place Guillaume II (nicknamed Knuedler), the main square in the centre of the city. The two-storey building is built in neoclassical style.

The Lëtzebuerg City Museum (before May 2017: Luxembourg City History Museum (French: Musée d'histoire de la Ville de Luxembourg)), illustrates the thousand-year history of the City of Luxembourg with both permanent and temporary exhibits. Founded on 22 June 1996, it was designed by Luxembourg architect Conny Lentz and Repérages, Paris.

The siege of Luxembourg, in which Louis XIV of France (husband of Maria Theresa of Spain) laid siege to the Spanish-controlled Fortress of Luxembourg from 27 April to 7 June 1684, was the most significant confrontation of the War of the Reunions between France and Spain. The action caused alarm among France's neighbours and resulted in the formation of the League of Augsburg in 1686. In the ensuing war France was forced to give up the duchy, which was returned to the Habsburgs by the Treaty of Ryswick in 1697.

The Fortress of Luxembourg (Luxembourgish: Festung Lëtzebuerg; French: Forteresse de Luxembourg; German: Festung Luxemburg) is the former fortifications of Luxembourg City, the capital of the Grand Duchy of Luxembourg, which were mostly dismantled beginning in 1867. The fortress was of great strategic importance for the control of the Left Bank of the Rhine, the Low Countries, and the border area between France and Germany. The fortifications were built gradually over nine centuries, from soon after the city's foundation in the tenth century until 1867. By the end of the Renaissance, Luxembourg was already one of Europe's strongest fortresses, but it was the period of great construction in the 17th and 18th centuries that gave it its fearsome reputation. Due to its strategic location, it became caught up in Europe-wide conflicts between the major powers such as the Habsburg–Valois wars, the War of the Reunions, and the French Revolutionary Wars, and underwent changes in ownership, sieges, and major alterations, as each new occupier—the Burgundians, French, Austrian and Spanish Habsburgs, and Prussians—made their own improvements and additions. Luxembourg took pride in the flattering historical epithet of the "Gibraltar of the North" as a result of its alleged impregnability. By 1443 it had only been taken by surprise by Philip the Good. In 1795, the city, expecting imminent defeat and for fear of the following pillages and massacres, surrendered after a seven-month blockade and siege by the French, with most of its walls still unbreached. On this occasion, advocating to extend the revolutionary wars across the French borders, the French politician and engineer Lazare Carnot explained to the French House of Representatives, that in taking Luxembourg, France had deprived its enemies of "...the best fortress in Europe after Gibraltar, and the most dangerous for France", which had put any French movement across the border at a risk. Thus, the surrender of Luxembourg made it possible for France to take control of the southern parts of the Low Countries and to annex them to her territory. The city's great significance for the frontier between the Second French Empire and the German Confederation led to the 1866 Luxembourg Crisis, almost resulting in a war between France and Prussia over possession of the German Confederation's main western fortress. The 1867 Treaty of London required Luxembourg's fortress to be torn down and for Luxembourg to be placed in perpetual neutrality, signalling the end of the city's use as a military site. Since then, the remains of the fortifications have become a major tourist attraction for the city. In 1994, the fortress remains and the city's old quarter were listed as a UNESCO World Heritage Site.

The Duchy of Luxembourg (Dutch: Luxemburg; French: Luxembourg; German: Luxemburg; Luxembourgish: Lëtzebuerg) was a state of the Holy Roman Empire, the ancestral homeland of the noble House of Luxembourg. The House of Luxembourg became one of the most important political forces in the 14th century, competing against the House of Habsburg for supremacy in Central Europe. They would be the heirs to the Přemyslid dynasty in the Kingdom of Bohemia, succeeding the Kingdom of Hungary and contributing four Holy Roman Emperors until their own line of male heirs came to an end and the House of Habsburg received the territories that the two Houses had originally agreed upon in the Treaty of Brünn in 1364. In 1443, the duchy passed to Duke Philip the Good of Burgundy of the French House of Valois, and, in 1477, by marriage to Archduke Maximilian I of Austria of the House of Habsburg. The Seventeen Provinces of the former Burgundian Netherlands were formed into an integral union by Holy Roman Emperor Charles V in the Pragmatic Sanction of 1549. In 1795, French revolutionaries ended this situation.

The Judiciary City (French: Cité judiciaire) is a site in Luxembourg City, in southern Luxembourg, that houses a number of courts and legal offices. It consolidates all of Luxembourg City's judicial buildings, except those related to the institutions of the European Union, on one site, and greatly expands their capacity. The City sits on the Saint-Esprit plateau, sandwiched between the Alzette and the Pétrusse, in the southern part of the central Ville Haute quarter. Its buildings are built in modern Moselle Baroque, to match the surrounding area, and were designed by Robert Krier. Planned since 1991, the first stone of the City was laid on 7 October 2003, and it was officially inaugurated five years later, on 6 October 2008. The buildings contain 43,000 square metres (460,000 sq ft) of floor space, including 300 offices and sixteen courtrooms.
