Mitte

Mitte is Berlin's historic core.

Berlin State Opera was destroyed in World War II.

French Cathedral, which is not a Cathedral and never has been, is a non-denominational (or multi-denominational) Protestant Church whose name reflect the fact that Frederick The Great spoke French and loved French Culture, which is ironic insomuchas Prussia aligned nominally against France in the Seven Years War.

Konzerthaus is yet another neo-Classical structure, looking kind of like a Greek Temple with Ionic Columns, adjacent Gendarmenmarkt.

Deutscher Dom is almost identical to Französischer Dom in history and purpose, except that it was profaned in 1996 and became a museum.
