The building was purchased on behalf of the government of the newly independent Polish nation in 1919 by the country's first ambassador to the United States, Prince Kazimierz Lubomirski.

In 1978 a team of specialists was brought from Poland to repair and renovate the ornate plaster and woodwork of the embassy's state rooms, returning the interior to its former grandeur and restoring its artistic integrity.

The instrument not only evokes memories of music played on it by outstanding musicians over the years, but, as a gift to the embassy during World War II from Ignacy Jan Paderewski, is also in itself a symbol of Polish patriotism.

Amongst these is an original oil-on-canvas portrait by Josef Grassi of Polish national hero Tadeusz Kościuszko, a Pole who after meeting with Benjamin Franklin in Paris proceeded to the United States to fight in the Revolutionary War and who ultimately went on to design the fortifications at West Point.

The consular section of the embassy, which deals with visa and passport matters to both Polish citizens and foreign nationals wishing to visit or emigrate to Poland, is located at 2224 Wyoming Avenue NW.
