The Potocki Palace in Lviv (Polish pronunciation: [pɔˈtɔt͡skʲi], Ukrainian: Палац Потоцьких, Palats Pototskykh; Polish: Pałac Potockich) was built in the 1880s as an urban seat of Alfred Józef Potocki, former Minister-President of Austria.
The first palace was built in the style of classicism, designed by architect Ignacy Chambrez [pl].
The project was modified by architects Julian Cybulski and Ludwik Baldwin-Ramułt and implemented under their guidance.
In 1851, in the town of Slavuta, Maria Klementyna Sanguszko (1830–1903) married Alfred Józef Potocki of the Pilawa Coat of Arms (1817–1889), an earl, political figure, marshal of the Galician Sejm, governor of the Kingdom of Galicia and Volodymyria, second ordynat of Łańcut.
The Potocki family had four children: Roman, Julia, Klementyna (married Tyszkiewicz) and Józef Mikołaj.
The building is made in the style of French classicism, brick, plastered, H-shaped in plan, with a developed central avant-corps and lateral wings.
The facades are decorated with figured window frames and rustication, moulded balconies and balustrades.
Some widely used features as part of decoration include stucco, gilding, coloured marble, valuable breeds of wood, painting.
On the southwest side near the palace, stables with bas-reliefs of horses and services were built with unpublished red brick, allowing for access to the Ossolinski Street (now Stefanik, 7a).
At the end of the 1980s, in the palace park, a mine was laid for laying underground tram tunnels, and built an unsightly annex, which now houses the Museum of Ancient Ukrainian Book Art (Copernicus Street, 15a).
On 22 November 1919, American pilot Edmund Graves dropped into the palace during an air show over the centre of Lviv on the 1st anniversary of the city's liberation.
The plane crash and the explosion of its fuel tanks caused a fire on the upper floors and the roof of the palace.
From 1945 to 1972 the palace was used by the Institute of Geology and Geochemistry of Combustible Minerals of the Academy of Sciences of the USSR.
