Château de Vincennes (French pronunciation: [ʃɑto d(ə) vɛ̃sɛn]) is a station on line 1 of the Paris Métro, situated on the border between the communes of Vincennes and the Bois de Vincennes, which is part of the 12th arrondissement of Paris. It is named after the nearby Château de Vincennes.
Paris Métro Line 1 (French: Ligne 1 du métro de Paris) is one of the sixteen lines of the Paris Métro. It connects La Défense in the northwest and Château de Vincennes in the southeast. With a length of 16.5 km (10.3 mi), it constitutes an important east–west transportation route within the City of Paris. Excluding Réseau Express Régional (RER) commuter lines, it is the busiest line on the network with 181.2 million travellers in 2017 or 496,000 people per day on average.
The line was the network's first to open, with its inaugural section entering service in 1900. It is also the network's first line to be converted from manually driven operation to fully automated operation. Conversion, which commenced in 2007 and was completed in 2011, included new rolling stock (MP 05) and laying of platform edge doors in all stations. The first eight MP 05 trains (501 through 508) went into passenger service on 3 November 2011, allowing the accelerated transfer of the existing MP 89 CC stock to Line 4;. The conversion allowed Line 1 to operate as the system's second fully automated line, after Line 14.
