This ancient gold shop dates back to the early 1900s and the reign of King Rama VI. Today, the seven-story late colonial-style building is still owned by its founding family, and in 2002 underwent a major renovation. Although the shop still deals gold on a day-to-day basis, a section has also been converted into a museum for the public. Be sure to call ahead one day in advance as they don’t allow walk-in visitors for security reasons.
