One of the main reasons travellers head to Suzhou is to explore its iconic classical gardens. Dating back to the 11th century, these picturesque horticultural hubs have earned their status as UNESCO World Heritage Sites as they all display the classic features of Chinese gardens. Cultivated and beautifully maintained for centuries, every garden combines the elements of water, stones, plants and architecture to create serene and lush enclaves like that of the Humble Administrator's Garden and the Lion Grove Garden. What's more, the Leaning Tower of China is also found here and is located atop a Buddhist temple that dates back to the 18th century. The tower, which is higher than Italy's own leaning tower also began leaning in the Ming Dynastic era.
