Background
Every territorial state has a capital where parliament, government and ministries are based. Potsdam lies right next to Berlin and is famous above all for Sanssouci Palace and its parks, a UNESCO World Heritage Site. “Brandenburg an der Havel” is a separate town – the state is named after it, but it is not the capital. Brandenburg lies in north-eastern Germany and completely surrounds the capital, Berlin. To the east it borders Poland.
Why are the other answers wrong?
Cottbus, Brandenburg, Frankfurt/Oder are also towns in Brandenburg, but not the state capital.
