The most famous and popular creative park in the area is IDEAL 166, which was once the renowned Hangzhou Silk Printing and Dying United Factory. It was the first silk factory to use machines for mass production after the founding of the People's Republic of China. It would be difficult to find a better place to start a creative firm. The factory, built in the 1950s, was designed by former Soviet Union experts and construction was supervised by German architects. With its unique wave-shaped roof, the building was ahead of its time. It was designated a municipal historical building under protection last year. IDEAL 166 attracts a large number of visitors for both its appearance and the shops on offer. All the offices within the creative park are carefully decorated with distinctive styles. And some firms have also opened their own shops, selling crafts and clothing. Various boutique shops filled with original products at fair prices are just minutes from each other.
