The mission of Lan Su Chinese Garden is to cultivate an oasis of tranquil beauty and harmony to inspire, engage and educate our global community in the appreciation of a richly authentic Chinese culture. Lan Su Chinese Garden is one of Portland's greatest treasures and most interesting sites to see while visiting Portland. Lan Su was built by Chinese artisans from Suzhou, China and is one the most authentic Chinese gardens outside of China. Much more than just a beautiful botanical garden, Lan Su is a creative wonder — a powerfully inspiring experience based on a 2,000-year-old Chinese tradition that melds art, architecture, design and nature in perfect harmony.
