The Cotroceni Palace was designed as the palace of residence for Ferdinand and Marie, the heir Prince and Princess to the
Romanian throne and was built between 1893-1895, by the French architect Paul Gottreau.
The palace reveals its magnificence right from the entrance. Its monumental interior staircase surrounded by vast galleries
in neo-baroque French style reminds one of the Great Opera in Paris, which, in fact, was used as a model. The French Paul Gottereau
chose a Venetian style and the architect Grigore Cerchez redesigned an entire wing of the palace, including the great reception hall, in Romanian romantic architectural style.
At Cotroceni, there exists also a hunting hall built in Italian Renaissance style, but also a royal library used for work-study by King Ferdinand himself.
The most impressive room in the new wing is the Union Hall, where the most important receptions of the president take place.
The hall has marble walls and numerous columns reminiscent of the original architecture of Văcărești Monastery.
The roof is a colourful stained glass with blue background, in which are depicted scenes from the national history. Part of the Cotroceni estate has been transformed into the Botanical Garden.
