If you find yourself doing a little cultural tour of Kowloon, Chi Lin Nunnery and Nan Lian Garden are quick and easy stops within short walking distance of each other. The two are located off the Diamond Hill MTR stop, much less of a hike from the train station than the less visited Kowloon Walled City Park (by far a more interesting visit, but brush up on its history before you go).
Chi Lin, a Buddhist temple complex, opens several of its buildings and its garden for free to the public daily. The entire complex uses traditional Chinese architectural techniques that allow for the buildings to be built without using a single nail; instead the building framework is constructed using a series of interlocking wood pieces.
Chi Lin designed and currently manages the Nan Lian Garden, built in the Tang Dynasty style. If it feels a bit manufactured, it is. But the garden does serve as a gathering space for events and exhibitions; check the website’s calendar for the latest ongoings.
