Hofburg Palace

Hofburg Palace is a palace located in Vienna, Austria, that has housed some of the most powerful people in European and Austrian history, including the Habsburg dynasty, rulers of the Austro-Hungarian empire. It currently serves as the official residence of the President of Austria. It was the Habsburgs' principal winter residence, as the Schönbrunn Palace was their preferred summer residence.
