List of districts in Budapest

Budapest, the capital of Hungary has 23 districts (), each with its own municipal government.
The number of districts in Budapest.
Budapest was organized into 10 districts (numbered from I to X) in 1873 after the unification of the cities of Pest, Buda and Óbuda. The districts at that time:
In the 1930s, 4 new districts were organized, numbered from XI to XIV. On 1 January 1950, 7 neighboring towns and 16 villages were annexed to Budapest by creating 9 new districts, so the number of its districts increased to 22. District IV was annexed to District V and the number IV was given to the northernmost newly merged town, Újpest. Former district borders were also partly modified but the old numbering system is still clear on the map. In 1994, Soroksár left District XX, became the newest district and received the number XXIII.
Districts.
Listed below are the ordinal numbers of the 23 districts of Budapest, their official names (if there is one), and the names of the neighbourhoods within the districts. Each district can be associated with one or more neighbourhoods named after former towns within Budapest.
Arrangement of districts.
District I is a small area in central Buda (the western side), including the historic Castle. District II is in Buda again, in the northwest, and District III stretches along in the northernmost part of Buda.
To reach District IV, one must cross the Danube to find it in Pest (the eastern side), also at north. With District V, another circle begins: it is located in the absolute centre of Pest. Districts VI, VII, VIII and IX are the neighbouring areas to the east, going southwards, one after the other.
District X is another, more external circle also in Pest, while one must jump to the Buda side again to find Districts XI and XII, going northwards. No more districts remaining in Buda in this circle, we must turn our steps to Pest again to find Districts XIII, XIV, XV, XVI, XVII, XVIII, XIX and XX (mostly external city parts), almost regularly in a semicircle, going southwards again.
District XXI is the extension of the above route over a branch of the Danube, the northern tip of a long island (Csepel-sziget) south from Budapest. District XXII is still on the same route in southwest Buda, and finally District XXIII is again in southernmost Pest, irregular only because it was part of District XX until the mid-90s.
