SINGAPORE - British architectural artist Stephen Wiltshire, known for his immense panoramic drawings of world cities, arrived in Singapore this week.

He began his week-long maiden visit with a tour on Monday of historical sites in Chinatown as well as the skyscrapers of the financial district.

Mr Wiltshire, who was diagnosed with autism at the age of three and travels with his older sister Annette, will be drawing a 4m long panorama of the city from memory. He will be at the Main Atrium of Paragon from Wednesday to Sunday, as part of a Singapore Press Holding's 30th anniversary celebration event called See The Big Picture.

"It's a nice city, it's very historic. But I like the tall buildings best," he said after Monday's tour.
