Какие ограничения Парижский конгресс 1856 г. наложил на Россию?

Dear Ann,
I visited London last summer. I'm really happy. We went there with our teacher. I saw a lot of interesting places in London. First of all I saw Big Ben and the Houses of Parliament, the Thames and the Tower of London. Just imagine it! Then I also saw  Westminster Abbey, Trafalgar Square with Nelson's Column and the British museum. My dream came true: I took a ride on the London Eye and soon after that I saw the Changing of the Guard near Buckingham Palace. Next week I will send you some photos of my trip   to London. How did you spend your last holidays? Keep in touch.
Yours,
Varya
