Unter den Linden crosses Museumsinsel (Museum Island) in the Spree River, home to several renowned art museums whose buildings date mostly from the eighteenth and early nineteenth centuries and are magnificent sights in and of themselves. They include Old Museum, New Museum, Alte Nationalgalerie (Old National Gallery), the Bode Museum, and the Pergamon Museum
Other must-see sights in the area include the Lustgarten, a vast park bordered on one side by the Berliner Dom. The Berlin State Opera, Humboldt University, and the Berlin State Library are among other institutions located along the boulevard.
Just south of Unter den Linden lies one of the most gorgeous squares in Europe: Gendarmenmarkt dates from the eighteenth century and is surrounded by towering historic buildings that will have architecture and history buffs in awe. The neoclassical Konzerthaus Berlin, the French Cathedral - Huguenot Museum and Deutscher Dom cathedrals are all in the area. As an ode to the sophisticated literary heritage of the country, a statue of the poet Friedrich Schiller stands in the center. The square comes alive in December for Berlin's most famous Christkindlmarkt, a festive, traditional street market held especially for Christmas.
