Ban Sao Nak (the house of many pillars) was built in 1895
by Mong Chan Ong Chandraviroj as a resident. The house
was designed in a combination of northern Thai and Burmese
architectures. The verandah around the house shows a
distinct Burmese architecture, while thhe roofs and general
structures are typical Lanna Thai. The wonder of the house
is that it is supported by 116 teak pillars. In front of the
house stand a huge 133 years old Sarapee (Ochocarpus
siamensis) tree.
