St.-Hedwigs-Kathedrale

Nazi Propaganda Minister Josef Goebbels made Bebelplatz (then called Opernplatz) infamous on 10 May 1933, when he used the square across from Humboldt University to burn 20,000 books by "immoral" authors of whom the Nazis did not approve. Their list included Thomas and Heinrich Mann, Arnold Zweig, Kurt Tucholsky and Sigmund Freud. Today a monument is the reminder, though it blames Nazi students for the episode. When entering the square it's easy to miss the monument. It is in that part of Bebelplatz bounded on one side by the Opera House and on the other side by Humboldt University. Look dead centre: the monument is underground. A piece of plexiglass allows the viewer to look underground into a large, white room, filled with entirely empty, blank white bookcases. The room is large enough to hold the 20,000 books that were burnt. The absence of books reminds the viewer just what was lost here: ideas. But the event did reveal things to come, as ethnically Jewish author and philosopher Heinrich Heine, whose books were burned, let one of his characters say in an 1821 play: "This was only the foreplay. Where they burn books, they will also burn people." He was correct.

The impressive building and royal history make the building alone worth a visit. The building reopened in December 2017 after extensive refurbishments and acoustic improvements. The general music director of the Staatsoper and its resident orchestra, Staatskapelle Berlin, is the conductor Daniel Barenboim.

Nice church near Unter den Linden/Museum Island, finished in 1830 by Schinkel in English Neogothic style. Nice exhibition inside (neoclassical statues and an exhibition about Schinkel's life and work upstairs).

Erected in 1818 to a classically-inspired design by Karl Friedrich Schinkel as a guardhouse for the imperial palace, since 1993 this compact building has housed a small, but extremely powerful war cenotaph, the Central Memorial of the Federal Republic of Germany, continuing its use under East German rule as the primary "Memorial to the Victims of Fascism and Militarism". The interior of the Doric column-fronted building is intentionally empty, but for a small but moving sculpture by Käthe Kollwitz depicting a mother cradling a dead child. The statue is positioned beneath a round hole in the ceiling, exposing the figures to the rain and snow.

The French cathedral houses the Hugenottenmuseum. It represents the ongoing influence on Berlin by the Huguenots who emigrated from France after the revocation of the Edict of Nantes. Crown Prince Friedrich William encouraged them to settle here because most of them were skilled workers or otherwise useful to the kingdom. One memorable artwork, in room nine of the museum, pictures Crown Princess Dorothea exclaiming "But he's a refugee!" upon being presented a very valuable set of jewels by Pierre Fromery. The generally agreed-upon view of refugees as poor, without resources let alone diamonds, was blown apart by the talented French Protestants forced to leave their country due to religion. One of the most notable effects of having such a large French population was their influence on the infamous Berlin dialect. Berlinerisch words such as Kinkerlitzchen (from French "quincaillerie" - kitchen equipment) and Muckefuck (from French "mocca faux" - artificial coffee, though that etymology is not universally accepted) are unique to the area. The Französischen Dom (cathedral) itself was built to resemble the main church of the Huguenots in Charenton, France, destroyed in 1688. It has housed the museum since 1929. Closed till 2019

German historical museum covering everything from pre-history up to the present day. One can spend many, many hours here! The building from 1695/1730 was the Zeughaus (Arsenal) until 1876.
