Nikolaevsky Palace (Nicholas Palace)
This palace was requested by Nicholas I for his third son, Grand Duke Nicholas Nikolaevich. Architect Andrei Stackenschneider, master of eclectism, was put in charge of the construction.
The construction of this building on Truda (work) Square, initially Annunciation Square, started in 1853 and ended in 1861. During this time the Grand Duke lived mostly in the Winter Palace.
When the Grand Duke died in 1891 the palace was bought by the crown. A few years later it hosted the Xenia Institute for Noble Young Ladies.
The institute was then replaced to the Labor Palace after the Revolution. Today it welcomes the council of Unions of Saint Petersburg and its region. The rest of the building was turned into offices.
