Am Kupfergraben 6, Revenue house in Dorotheenstadt, Berlin, Germany

Am Kupfergraben 6 is a five-storey neoclassical building on the street Am Kupfergraben in Berlin's Mitte district, not on Museum Island. Its pale ochre facade rises from a grey ground floor, with six windows on each of the first three upper storeys and small square windows under a red-tiled mansard roof. The name "SUNGA-TSCHI" is mounted above the ground-floor entrance.

The building is a listed four-storey house on the Spree canal side of Am Kupfergraben, in the Dorotheenstadt quarter; the street itself was first built up around 1580, and most of its houses went up in the 18th century after the Spree arm was regulated. By 2020 it held the home of former chancellor Angela Merkel and her husband Joachim Sauer, and until his death in April 2013 the flat of SPD politician Ottmar Schreiner; Lothar de Maizière's law office was also housed here.
