If you go to St Petersburg, what places would you like

If I were in St. Peterburg, at first I will go to State Hermitage Museum. It is one of the biggest art museum.
Then I will visit the Saint Isaacs Cathedral. There are very beautiful architecture and picturesque park.
The next place, which I would like to see is Peter-Pavels Fortress. It is located on the island in the Neva River. It was built in the 18th century and we can still observe its beauty.
The last place is The Neva Embankment. I would like to be there at night, when the lights are already on fire and there are amazing views.
