Unter den Linden
Unter den Linden runs east–west from the site of the Stadtschloss royal palace (main residence of the House of Hohenzollern) at the Lustgarten park, where the demolished Palace of the Republic once stood, to Pariser Platz and Brandenburg Gate. Eastward the boulevard crosses the Spree river at Berlin Cathedral and continues as Karl-Liebknecht-Straße. The western continuation behind Brandenburg Gate is Straße des 17. Juni. Major north–south streets crossing Unter den Linden are Friedrichstraße and Wilhelmstrasse.
