I spent most of my summer holidays travel in London. I arrived there in middle of July. After reaching my sister’s apartment I got many sleep. The next day I went to St Paul’s Cathedral, an amazing monument, that was well worth a visit. After take some photos in front of it, I moved on to the Tate Modern art gallery. There is an excellent exhibition of oil paintings and sculptures by some famous British artist. For dinner we went to the Ivy, a very beautifully restaurant. The food was good but the atmosphere was nice. It was a great day of sightseeing and one that would never be forgotten it.
