In London, I enjoyed and found a very nice place to enjoy Baroque paintings. It is the Buckingham Palace. Do you know why? The State Room of the palace has Her Majesty's collection that includes many masterpieces by Titiano, Rembrandt, Goya, van Dych, Canaleti, Turner, Tiepolo, etc. I stayed inside the Art Institute of the University of London that has a great collection of Lucas Cranach's Adam and Eva, Doga, Cezanne, van Gogh's popular self portrait with an ear bandage, Kandinsky's very late late paintings. Actually, some pieces are much better than what the National Gallery has.
The National Gallery shows you with very popular pieces like Cranach's Cupid and Venus, Goya's Felipe IV portrait, etc. But, They are somehow British-like styles; let's say very moderate and not out-spoken (you see, right). Maybe, the No. 1 of art the UK holds is gardening, not paintings or music.
I found a tremendously huge number of gardens in universities which I paid a visit to. I really admire British gardens in which you may enjoy very nice tea and scorns. I cannot finish a day without the stuff anymore. I have got already addicted with tea and clotted cream. I am really crazy about them.
