The boulevard received its name the from the Linden trees planted alongside it. In recent years, the boulevard has been extensively renovated.
Unter den Linden Boulevard, meaning "under the trees" in German, stretches for about a kilometer and a half. On both sides are some of the city's most important sites and buildings. One can see so many intriguing sites and architectural monuments that stand in its vicinity.
From there you can see Humboldt University - the first university in Berlin, the Opera Building and the Academy of the Arts, the Berliner Dom, the Guggenheim Gallery, as well as the Alexanderplatz to the east, with the TV Tower attached to it, the Reichstag Gate, the Holocaust Memorial to the West and the Friedrichstrasse shopping street across it.
But this boulevard, with its neo-classical structures, is not only beautiful. Here, one of the most difficult historical events in modern history took place. In the square of Bebelplatz, opposite Humboldt University, in 1933 the burning of the books took place, in which the Nazis set fire to thousands of books whose contents were against their distorted ideology.
