The House of Opium is a small private museum established by Mrs. Phatcharee Srimathayakun who was born in Chiang Saen District. After graduating from the Faculty of Education, Chulalongkorn University and living in Bangkok and Chiang Mai, she returned to her birthplace in order to open an antique shop and a small guest house in 1987. She was interested in local history. She began collecting artistic objects and studying the opium trade in the Golden Triangle by reading books on opium, documents provided by Thailand’s Narcotics Control Board, and university studies. She lived with tribal people from the Hill tribe, Shan, Lu, Burmese and Lao who migrated to the village and nearby areas. She saw that their antiques were historical, artistic and culturally valuable.

     Phatcharee knew that if these antiques are not preserved, they may be all bought and dispersed by foreign collectors. Therefore, in 1989, she opened House of Opium museum to display opium artifacts and combine the interesting stories of opium in the Golden Triangle with information and translation support from scholars at Mahidol University and Chulalongkorn University. The name, “House of Opium” was given by Khun Rong Wongsawan, a writer and national artist.

     In the beginning, House of Opium had simple exhibitions in its bamboo building with thatched roof. There were about 300 opium tools. The exhibitions including cupboards, lighting system and handmade dolls, were prepared and descriptions were written by the vocational students from Udon Thani Vocational College. Initially, the admission fee was five baht per person. A small souvenir jade piece was also given to each visitor.

     In 1992, Phatcharee renovated the building and exhibitions with the supports from Chiang Rai artists including Preecha Ratchawong and Narongdej Sudjai, who drew pictures presenting the legends and relationships between opium and hill tribes. The admission fee was increased to 10 baht per person, and then 20 baht in 1997.

     In 2007, Phatcharee established the House of Golden Triangle Partnership and renovated the building again. Over 1,500 antiques that had been collected for almost 20 years were exhibited and the admission fee was increased to 50 baht per person.

     In 2019, House of Opium celebrated its 30-year anniversary. There are 2,000 additional artistic objects. There are new zones including the simulated opium poppy field room, six tribal dolls and smoking tools. The presentations are also simplified, preserving the concept of a small museum while providing a comprehensive knowledge of opium in the Golden Triangle through its valuable antiques. The admission fee remains affordable (50 baht).
