The "Khum Vichai Raja: Ancient Mansion, Legend of Phrae" sign is a teak carved signage situated in front of the historic mansion. The phrase "Legend of Phrae" emphasizes the house's role as a living witness to major historical events, such as the Ngiao Rebellion, and as the former residence of high-ranking nobility who shaped Phrae’s social foundation. This sign serves as more than just a nameplate; it acts as a gateway to the tales of "Gingerbread Architecture" and the aristocratic lifestyle of the past that still resonates within the city today.
