Unification of three older cities

Budapest

153 yearsfrom 1873 CE to 2026

Budapest was formed in 1873 by uniting Buda, Óbuda and Pest. Each had a much older history. The Danube connected the new capital's different communities, making its municipal age much younger than its settlements.

Remember, celebrate, explore

The unification anniversary is 17 November. Compare the different riverbanks to understand the three-city story.

Hong Kong

Mexico City

701 yearsfrom 1325 CE to 2026

Medieval city charter milestone

Vienna

805 yearsfrom 1221 CE to 2026
