Vienna is 414.78 km² holding 2,028,499 people, and almost everything a visitor comes for sits inside a single ring road less than a kilometre across.
The Innere Stadt — the 1st district — is the medieval core, and the Ringstrasse that surrounds it was built in the second half of the nineteenth century on the line of the demolished bastions. The 371-hectare historic centre has been a UNESCO World Heritage Site since 2001; it was on the endangered list from 2017 to 2026.
The wider urban area holds 2,223,236 people and the metropolitan area 2,890,577, which makes Vienna the tenth largest city in Europe and by a long way the largest in Austria.

District boundaries come from OSM administrative relations, so a district page holds exactly the places inside it — plus, for the islands and the coast, the nearest district by proximity.
Twenty-three districts, numbered roughly in the order they were absorbed, arranged around the 1st.
The Innere Stadt is the 1st and holds the cathedral, the Hofburg, the opera and most of what a short visit will see. Districts 2 to 9 and 20 were incorporated in 1850 and lie inside the Gürtel, the outer ring road; they are the inner districts and are where most visitors sleep and eat. Districts 10 to 19 and 21 to 23 came in between 1874 and 1938, mostly in 1892.
Districts 21 and 22 are across the Danube on the left bank — Floridsdorf is the northernmost part of the city and Donaustadt the largest by area. Districts 2 and 20 sit on the island between the Danube and the Donaukanal.
The postal code gives the district: 1XXA, where the middle two digits are the district number. An address at 1070 is in the 7th.

The U-Bahn, the trams, and a ticket that covers both.
The U-Bahn has five lines, 109 stations and 83.9 km of track, and it opened on 25 February 1978. It carried 404.8 million passengers in 2023. Trains run from about 05:00 to 01:00 at intervals of two to fifteen minutes, and run all night at fifteen-minute intervals on Friday and Saturday nights and before public holidays.
A sixth line, the U5, is under construction for completion between 2026 and 2032; the network will then be 90 km with 116 stations.
Tickets are integrated with the trams, the buses and the S-Bahn through the VOR system, so one ticket covers the whole journey. Some airport services are outside it.
Inside the Ring, walking beats all of it.

Three to four. Two days cover the Innere Stadt and the Ring — the cathedral, the Hofburg, the opera, the museums on the Maria-Theresien-Platz. A third takes Schönbrunn and the Belvedere, and a fourth allows a proper concert or an afternoon in the wine villages.
Twenty-three of them, numbered roughly in the order they joined the city. The 1st is the medieval centre, districts 2–9 and 20 came in 1850 and lie inside the Gürtel, and the rest arrived between 1874 and 1938. The postal code carries the number: 1070 is the 7th district.
