The Great Gatchina Palace..St Petersburg Russia

     The Great Gatchina Palace   was built in 1766–1781 in Gatchina town (Russia) by Antonio Rinaldi for Count Grigori Grigoryevich Orlov who was a favourite of Ekaterina II. The Gatchina Palace is located on the hill above Lake Serebryannoe. It combines themes of a medieval castle and a country residence. Palace interiors are exemplary of Russian classicism at the turn of 18th—19th centuries. The Gatchina Palace was one of the favourite residences of the Imperial family.

  
Catherine the Great took such a great liking of the Gatchina Palace and park, that at Orlov's death in 1783, she bought it from his heirs and presented it to her son, the future Emperor Paul I.
Paul I was the master of Gatchina for eighteen years. He invested considerable resources and used his experience from his travels around Europe to make Gatchina an exemplary palace and town. During the 1790s, Paul expanded and rebuilt much of the palace, and renovated interiors in the sumptuous Neoclassical style (illustration, left). Paul I graced the park with numerous additions, bridges, gates, and pavilions, such as "The Isle of Love" , "The Private garden", "The Holland garden" and "The Labyrinth" among many other additions. In 1796, after the death of his mother, Catherine the Great, Paul became Emperor Paul I of Russia, and granted Gatchina the status of Imperial City ( official residence of the Russian Emperors.)
A remarkable monument of Paul's reign is the Priory Palace   on the shore of the Black Lake. Constructed for the Russian Grand Priory of the Order of St John, it was presented to the Order by a decree of Paul I of Russia dated 23 August 1799.
After Paul's death the grand palace and park were owned by his widow, Maria Feodorovna, from 1801 to 1828. Paul's son, Nicholas I, was the master from 1828 to 1855. He made the most significant expansion of the palaces and parks, adding the Arsenal Halls to the main palace. The Arsenal Halls served as the summer residence of the emperor. In 1851, Nicholas I erected a monument to his father, Paul I, in front of the Palace. In 1854 the railroad between St. Petersburg and Gatchina was opened. At that time the city of Gatchina's territory was expanded by incorporation of several villages and vicinity.
Alexander II of Russia used Gatchina Palace as his second residence. He built a hunting village and other additions for his Imperial Hunting Crew, and turned the area south of Gatchina into a retreat where the Tsar and his guests could indulge in living in the unspoiled wilderness and of northwestern Russia. Alexander II also made updates and renovations in the main Gatchina Palace.
Alexander III of Russia made Gatchina his primary residence, after experiencing the shock and stress of his father's assassination. The palace became known as 'The Citadel of Autocracy' after the Tsar's reactionary policies. He lived most of his time in Gatchina Palace. Here he signed decrees and held diplomatic receptions, theatrical performances, masquerades and costumed balls, and other events and entertainment. Alexander III introduced technological modernizations in the Gatchina Palace and parks such as electric lights, a telephone network, non-freezing water pipes and a modern sewage system.
Nicholas II, the last Russian tsar, spent his youth in the Gatchina Palace. His mother, Empress Maria Feodorovna, widow of Alexander III, was the patron of the city of Gatchina and Gatchina Palace and parks.
