Between the River Seine and the rail yards attached to Gare de Lyon and Gare de Bercy is a green space which would seem pretty huge if the 12th weren't also the home of the Bois de Vincennes. The park is a good place to hang out waiting for the line to form for sporting events and concerts at AccorHotels Arena.

Built in 1625, the Hotel de Sully is an interesting house with some sculptures in a beautiful courtyard. The house features special exhibitions, so check listings when in Paris.

Reopened after extensive renovations, this small museum near the Louvre houses the Jean Walter and Paul Guillaume Collection, sold to the French Republic on very generous terms and numbering 143 paintings from the late 19th century and the first half of the 20th century (15 Cézannes, 24 Renoirs, 10 Matisses, 12 Picassos, 28 Derains, 22 Soutines). The collection joined the eight immense Water Lilies that Monet gave France in 1922 and which have been displayed since 1927 in two huge oval rooms purpose-built on the artist's instructions.

The oldest planned square in Paris, and what many tourists as well as locals consider the heart of the Marais area.

Famous people who stayed here include Marie de Rohan, intriguer during the Fronde; Jeanne Baptiste d'Albert de Luynes, future mistress of a duke of Savoy; Marie Angélique de Fontanges, mistress of Louis XIV, died here giving birth to his child who also died. Today its main cloister (illustration) forms part of the modern Hôpital Cochin.

One of the best-known and most beautiful churches in Paris, in the guise of a Corinthian order classical temple. Construction started in 1764, although the church was not finally consecrated until 1845. The Madeleine has a lavish interior of marble and gold.

This iconic triumphal arch forms the focus of the main east-west road axis of Paris, running between the Louvre and the Grande Arche de la Défense in the west. The monument was commissioned by Napoleon in 1806 as a tribute to his victories as Emperor of France - it was finally completed in 1836, long after his death. 50 m (150 ft) high and 45 m wide, the Arc de Triomphe is decorated with battle scenes and martial sculptures that includes La Marseillaise by Rude. The Tomb of the Unknown Soldier was placed beneath the arch in 1920, where an eternal flame burns in tribute to the French dead of both World Wars. The arch is surrounded by a large roundabout, aptly known as l'Etoile - 'the star' - with 12 thoroughfares leading off from it. Visitors can purchase a ticket to climb to the top of the arch, from where magnificent views spread out over western Paris. Admission to a small museum devoted to the history and meaning of the monument is included. The central island and the arch are accessed by an underground passage. Do not attempt to negotiate by foot the busy multi-lane road that rings the Arc de Triomphe, which many Parisian drivers seem to consider their own personal speedway.

The official residence of the President of France since 1848. Dating to the early 18th century, it contains the office of the President and the meeting place of the Council of Ministers. It is located near the Champs-Élysées in the 8th arrondissement of Paris, the name Élysée deriving from Elysian Fields, the place of the blessed dead in Greek mythology. Not open to the public, except occasionally during the annual National Heritage Days (usually a weekend in mid-September). Important foreign visitors are hosted at the nearby Hôtel de Marigny, a palatial residence.

a Roman Catholic church on the east side of the Place Saint-Sulpice within the rue Bonaparte, in the Luxembourg Quarter of the VIe arrondissement. At 113 metres long, 58 metres in width and 34 metres tall, it is only slightly smaller than Notre-Dame and thus the second largest church in the city. It is dedicated to Sulpitius the Pious. During the 18th century, an elaborate gnomon, the Gnomon of Saint-Sulpice, was constructed in the church. In front of the church itself is the magnificent Place Saint-Sulpice which contains the 'Fountain of the Four Bishops'. The church has a long-standing tradition of talented organists that dates back to the eighteenth century. In 1862, Aristide Cavaillé-Coll reconstructed and improved the existing organ built by François-Henri Clicquot. Though using many materials from Clicquot's French Classical organ, it is considered to be Cavaillé-Coll's magnum opus, featuring 102 speaking stops, and is perhaps the most impressive instrument of the romantic French symphonic-organ era. Its organists have also been renowned, starting with Nicolas Séjan in the 18th century, and continuing with Charles-Marie Widor (organist 1870-1933) and Marcel Dupré (organist 1934-1971), both great organists and composers of organ music. The current organists are 'titulaire' Daniel Roth (since 1985) and 'assistant titulaire' Sophie-Véronique Cauchefer-Choplin. In Saint-Sulpice Sunday organ recitals are held on a regular basis (Auditions du Dimanche, following the High Mass, usually from 11:30am till 12:05pm, during the subsequent mass, a visit of the organ loft is possible).

If you were a city planner in one of the great cities of our Earth and you discovered that a railroad right-of-way had been abandoned and would never be used again what might you do? Perhaps if you knew your stuff you'd convert it into a 4 mile long park, about half of which is elevated above street level on the old rail viaduct. This long narrow park pretty much allows the visitor to walk in carfree bliss from Place de Bastille to the Bois de Vincennes.

A Gothic church tower in a square 150m to the west of the Hôtel de Ville was restored by Ballu, is all that remains of Eglise Saint-Jacques-de-la-Boucherie, which was the meeting place in Paris for pilgrims heading to Santiago de Compestela. As such it is included on the UNESCO World Heritage List as part of the Routes of Santiago de Compostela in France.

Once the dye works for royalty, it is now a museum.

An ancient Roman theater, the only surviving above-ground ruins of the Gallo-Roman era in Paris (ancient Lutetia, French Lutèce) apart from the nearby Thermes de Cluny. The theatre could hold approximately 15,000 spectators and measures some 132 m x 100 m. Built sometime in the 2nd century CE, the location of the actor's dressing room, the platform of the stage, and lapidary remains can still be seen. The remains were rediscovered in 1869, when new streets were being built. An excavation was subsequently ordered in 1883. The theatre has been preserved as a quiet archaeological park removed from the bustle of Parisian streets.

The C.I.U.P. is a student quarter established in 1925, providing homes for about 10,000 students, scientists, and artists from 120 countries. It has 40 houses attributed to individual nations. The individual houses organise top quality cultural and political events. Among the most remarkable buildings are the Fondation Deutsch de la Meurthe, the Heinrich Heine House (Maison Heinrich Heine - Fondation de l'Allemagne), the Swedish Student House (Maison des Etudiants Suédois), and the Swiss Pavilion (Pavillon Suisse) which was built in 1933 on plans of Le Corbusier.
