<P> The twenty arrondissements are arranged in the form of a clockwise spiral (often likened to a snail shell), starting from the middle of the city, with the first on the Right Bank (north bank) of the Seine . Lyon and Marseille have, more recently, also been subdivided into arrondissements . </P> <P> In French, notably on street signs, the number is often given in Roman numerals . For example, the Eiffel Tower belongs to the VIIe arrondissement while Gare de l'Est is in the Xe arrondissement . In daily speech, people use only the ordinal number corresponding to the arrondissement, e.g. "Elle habite dans le sixième", "She lives in the 6th (arrondissement)". </P> <Table> <Tr> <Th> Arrondissement (R for Right Bank, L for Left Bank) </Th> <Th> Name </Th> <Th> Area (in km2) </Th> <Th> Population (March 1999 census) </Th> <Th> Population (July 2005 estimate) </Th> <Th> Density (2005) (in h . per km2) </Th> <Th> Peak of population </Th> </Tr> <Tr> <Td> 1st (I) R </Td> <Td> Louvre </Td> <Td> 1.826 km (0.705 sq mi) </Td> <Td> 16,888 </Td> <Td> 17,700 </Td> <Td> 9,693 </Td> <Td> before 1861 </Td> </Tr> <Tr> <Td> 2nd (II) R </Td> <Td> Bourse </Td> <Td> 0.992 km (0.383 sq mi) </Td> <Td> 19,585 </Td> <Td> 20,700 </Td> <Td> 20,867 </Td> <Td> before 1861 </Td> </Tr> <Tr> <Td> 3rd (III) R </Td> <Td> Temple </Td> <Td> 1.171 km (0.452 sq mi) </Td> <Td> 34,248 </Td> <Td> 35,100 </Td> <Td> 29,974 </Td> <Td> before 1861 </Td> </Tr> <Tr> <Td> 4th (IV) R </Td> <Td> Hôtel - de-Ville </Td> <Td> 1.601 km (0.618 sq mi) </Td> <Td> 30,675 </Td> <Td> 28,600 </Td> <Td> 17,864 </Td> <Td> before 1861 </Td> </Tr> <Tr> <Td> 5th (V) L </Td> <Td> Panthéon </Td> <Td> 2.541 km (0.981 sq mi) </Td> <Td> 58,849 </Td> <Td> 60,600 </Td> <Td> 23,849 </Td> <Td> 1911 </Td> </Tr> <Tr> <Td> 6th (VI) L </Td> <Td> Luxembourg </Td> <Td> 2.154 km (0.832 sq mi) </Td> <Td> 44,919 </Td> <Td> 45,200 </Td> <Td> 20,984 </Td> <Td> 1911 </Td> </Tr> <Tr> <Td> 7th (VII) L </Td> <Td> Palais - Bourbon </Td> <Td> 4.088 km (1.578 sq mi) </Td> <Td> 56,985 </Td> <Td> 55,400 </Td> <Td> 13,552 </Td> <Td> 1926 </Td> </Tr> <Tr> <Td> 8th (VIII) R </Td> <Td> Élysée </Td> <Td> 3.881 km (1.498 sq mi) </Td> <Td> 39,314 </Td> <Td> 38,700 </Td> <Td> 9,972 </Td> <Td> 1891 </Td> </Tr> <Tr> <Td> 9th (IX) R </Td> <Td> Opéra </Td> <Td> 2.179 km (0.841 sq mi) </Td> <Td> 55,838 </Td> <Td> 58,500 </Td> <Td> 26,847 </Td> <Td> 1901 </Td> </Tr> <Tr> <Td> 10th (X) R </Td> <Td> Entrepôt </Td> <Td> 2.892 km (1.117 sq mi) </Td> <Td> 89,612 </Td> <Td> 88,800 </Td> <Td> 30,705 </Td> <Td> 1881 </Td> </Tr> <Tr> <Td> 11th (XI) R </Td> <Td> Popincourt </Td> <Td> 3.666 km (1.415 sq mi) </Td> <Td> 149,102 </Td> <Td> 152,500 </Td> <Td> 41,598 </Td> <Td> 1911 </Td> </Tr> <Tr> <Td> 12th (XII) R </Td> <Td> Reuilly </Td> <Td> 16.324 km (6.303 sq mi) 1 6.377 km (2.462 sq mi) 2 </Td> <Td> 136,591 </Td> <Td> 138,300 </Td> <Td> 8,472 1 21,687 2 </Td> <Td> 1962 </Td> </Tr> <Tr> <Td> 13th (XIII) L </Td> <Td> Gobelins </Td> <Td> 7.146 km (2.759 sq mi) </Td> <Td> 171,533 </Td> <Td> 181,300 </Td> <Td> 25,371 </Td> <Td> 2005 </Td> </Tr> <Tr> <Td> 14th (XIV) L </Td> <Td> Observatoire </Td> <Td> 5.621 km (2.170 sq mi) </Td> <Td> 132,844 </Td> <Td> 134,700 </Td> <Td> 23,964 </Td> <Td> 1954 </Td> </Tr> <Tr> <Td> 15th (XV) L </Td> <Td> Vaugirard </Td> <Td> 8.502 km (3.283 sq mi) </Td> <Td> 225,362 </Td> <Td> 232,400 </Td> <Td> 27,335 </Td> <Td> 1962 </Td> </Tr> <Tr> <Td> 16th (XVI) R </Td> <Td> Passy </Td> <Td> 16.305 km (6.295 sq mi) 3 7.846 km (3.029 sq mi) </Td> <Td> 161,773 </Td> <Td> 149,500 </Td> <Td> 9,169 3 19,054 </Td> <Td> 1962 </Td> </Tr> <Tr> <Td> 17th (XVII) R </Td> <Td> Batignolles - Monceau </Td> <Td> 5.669 km (2.189 sq mi) </Td> <Td> 160,860 </Td> <Td> 160,300 </Td> <Td> 28,277 </Td> <Td> 1954 </Td> </Tr> <Tr> <Td> 18th (XVIII) R </Td> <Td> Butte - Montmartre </Td> <Td> 6.005 km (2.319 sq mi) </Td> <Td> 184,586 </Td> <Td> 188,700 </Td> <Td> 31,424 </Td> <Td> 1931 </Td> </Tr> <Tr> <Td> 19th (XIX) R </Td> <Td> Buttes - Chaumont </Td> <Td> 6.786 km (2.620 sq mi) </Td> <Td> 172,730 </Td> <Td> 187,200 </Td> <Td> 27,586 </Td> <Td> 2005 </Td> </Tr> <Tr> <Td> 20th (XX) R </Td> <Td> Ménilmontant </Td> <Td> 5.984 km (2.310 sq mi) </Td> <Td> 182,952 </Td> <Td> 191,800 </Td> <Td> 32,052 </Td> <Td> 1936 </Td> </Tr> </Table> <Tr> <Th> Arrondissement (R for Right Bank, L for Left Bank) </Th> <Th> Name </Th> <Th> Area (in km2) </Th> <Th> Population (March 1999 census) </Th> <Th> Population (July 2005 estimate) </Th> <Th> Density (2005) (in h . per km2) </Th> <Th> Peak of population </Th> </Tr>
