It turned out to be a swamp, silted up by floods that flooded Tyburn during the flood season. In 603, James I was crowned. He ordered people to drain water from marshes, build forest gardens, keep tropical animals such as camels, crocodiles and elephants, and build bird cages in the south to keep exotic rare birds. To the west is Buckingham Palace, to the north is St. James s Palace, to the East is Horse Guards, and to the south is Birdcage Walk. There are one lake and two islands in the park. They are St. James Park Lake, Duck Island and West Island. There is a small bridge on the lake. The Buckingham Palace surrounded by forest springs is visible to the West and the Foreign and Commonwealth Office Building is visible to the east. From east to west, St. James Park, Green Park, Hyde Park and Kensington Garden continue to form a chain of large forest gardens in central London. Various kinds of herbal crabapples are planted in the park. Among the cherry blossoms, peach blossoms and crabapple blossoms in early spring, I personally like the woody crabapple blossoms best, and have always regarded the woody crabapple as the most representative of China. Seeing this European-style herbal crabapple, I was fascinated by its beautiful and huge flowers, and really liked it. Blue morning glory with morning dew wrapped around the iron fence. The Lake in the middle of the park is called Swan Lake. Several tourists were feeding pigeons by the lake, and we poured out biscuit crumbs.
