Thailand's largest museum with Buddhist art, royal regalia, and artefacts spanning 2,000 years.
Royal barges, ancient weapons, ceramics, Buddhist sculpture from every period of Thai history, royal funeral chariots — the collection is vast.
Multiple buildings spread across a large compound near the Grand Palace — plan 2–3 hours minimum to do it justice.
The Phra Sihing Buddha statue (very sacred), the collection of royal funeral chariots (enormous and elaborate), Dvaravati (Mon) period sculpture.
Entry: 200 THB; closed Monday and Tuesday; free guided tours in English Wed–Thu at 9:30 AM — worthwhile if available.
