This sign explains the history of the ancient house of Mr. Lueang (Teuang) Sorin in Tha Rae, Sakon Nakhon Province. Constructed in 1932, it's a European-style mansion with a French-Vietnamese influence. It was built using traditional techniques, with a mixture of lime mortar, resin, and sugarcane juice used instead of cement. Decorative materials and metal fittings were imported from France by ship and train, showcasing the ingenuity of Vietnamese craftsmen and the prosperity of bygone eras.
