In 1802, Turner travelled around Europe, visiting France and Switzerland. He also went to the Louvre in Paris. During his life, he often travelled across Europe, visiting Venice in Italy several times. As his personal style developed, he began to produce paintings that were generalised or exaggerated in form and colour, rather than realistic or detailed. These caused much argument as to their artistic value, but nowadays are his best loved works. On his death, he left 300 oils and 20,000 watercolours to the British nation. Some of his watercolours are the most abstract or generalised of his paintings.
