20th arrondissement of Paris in the context of "Porte de Vincennes (Paris Métro)"

Paris Métro Line 3bis (French: Ligne 3 bis du métro de Paris) is one of the sixteen currently open lines of the Paris Métro. This short shuttle connects Gambetta and Porte des Lilas in the 20th arrondissement, east of Paris. With a length of 1.3 kilometres (0.81 mi) and four stations, this is the shortest line currently open in the network. It is also the least used line, with just over 1.6 million passengers in 2003, behind Line 7bis's 3.5 million.

The line was constructed in one block during the 1910s as an extension to Line 3, but the two parts were disconnected in 1971 when Line 3 was extended to Bagnolet - Gallieni, following the same fate as the Danube branch of Line 7 which became Line 7bis four years prior. From then on the line, now dubbed 3bis, was operated separately. As of 2010, six MF 67 trains, each shortened to three cars, run on the line.

Père Lachaise Cemetery (French: Cimetière du Père-Lachaise [simtjɛʁ dy pɛʁ laʃɛːz], formerly Cimetière de l'Est, lit. 'Cemetery of the East') is the largest cemetery in Paris, France, at 44 hectares (110 acres). With more than 3.5 million visitors annually, it is the most visited necropolis in the world.

The Père Lachaise is located in the 20th arrondissement and was the first garden cemetery, as well as the first municipal cemetery in Paris. It is also the site of three World War I memorials. The cemetery is located on the Boulevard de Ménilmontant. The Paris Métro station Philippe Auguste on Line 2 is next to the main entrance, while the station Père Lachaise, on both Line 2 and Line 3, is 500 m (1,640 ft) away near a side entrance.

Jules Barthoux or Jules Couyat-Barthoux (1881-1965) was a French geologist and archaeologist born in Etroussat in 1881. He excavated the sites of Bagram, Hadda and Ai-Khanoum in Afghanistan, as part of the French Archaeological Delegation in Afghanistan (DAFA), between 1925 and 1928. He died in 1965 in the 20th arrondissement of Paris, in Paris, France.

He and Pierre Montet worked in Cairo together in 1911.

The Directorate General for External Security (French: Direction générale de la Sécurité extérieure, DGSE) is France's foreign intelligence agency, equivalent to the British MI6 and the American CIA, established on 27 November 1943. The DGSE safeguards French national security through intelligence gathering and conducting paramilitary and counterintelligence operations abroad, as well as economic espionage. The service is currently headquartered in the 20th arrondissement of Paris, but construction has begun on a new headquarters at Fort Neuf de Vincennes, in Vincennes, on the eastern edge of Paris.

The DGSE operates under the direction of the French Ministry of Armed Forces and works alongside its domestic counterpart, the DGSI (General Directorate for Internal Security). As with most other intelligence agencies, details of its operations and organization are classified and not made public.
