You can see the plan of the palace online, on the official webiste of the Hermitage. I decided to upload the informational plans of the museum that you can take near the information stand after purchasing the tickets in the ticket booths. The maps are available on several languages.
On the 1st (lowest floor) of the Hermitage you can see the following:
- Antiquities from Siberia;
- Exhibits from Central Asia;
- Ancient Egypt;
- Earliest Eurasian art and culture;
- Ancient near east.
More detailed information can be found via official website of the Hermitage and also in Wikipedia.
Personally, I prefer to start my tour around the Hermitage from the 2nd floor, i recommend going there through the Main staircase of the Hermitsge, in order to feel the power and majesty of the palace which used to impress the Imperial guests and will amaze you, too.
On the 2nd floor of the Hermitage you can see the exhibits of:
- Russian culture;
- Palace interiors;
- French art: XVth-XXth centuries;
- Spanish art;
- German art;
- British art;
- Flemish art;
- Dutch art;
- Netherlandish art;
- Italian art;
- European medieval art;
- European arms and armour.
Try not to miss the temporary exhibitions held in the Armorial and Picket halls, they are absolutely interesting (in my last visits there were shown the restored museum exhibits. Awesome works of art!)
On the 3rd floor of the Hermitage you can see the objects of*:
- European art: XIXth-XXth centuries;
- French art: XIXth-XXth centuries;
- Byzantine art and art of the near East;
- Art of the far East and art of Central Asia.
*the stated collections were actual for november 2014. Some of the exhibits of the Impressionists (Francis Bacon, Matisse) are in the General Staff buiding now.
