Marvel at the Solid Gold Cochin Royal Crown: The undisputed highlight of the main museum building is the heavy royal vault, which houses the priceless, solid gold crown of the Cochin Maharajas. Embellished with large, precious diamonds, rubies, and emeralds, this legendary piece of regalia was gifted to the royal house by European trade partners. Walking through the high-security gallery also reveals a stunning array of royal jewelry, heavy gold ornaments, and diamond-studded ceremonial breastplates worn during formal durbars.

Explore the Weaponry and Armory Gallery: History and martial arts enthusiasts can tour an impressive collection of ancient weapons used by the royal guard. The gallery displays intricately carved brass-hilted swords, heavy iron maces, antique shields, and traditional flexible steel swords (Urmi) utilized in ancient Kalaripayattu combat. The displays also feature early European and Middle Eastern firearms, flintlock pistols, and heavy ceremonial cannons positioned along the stone courtyards.

Admire Epigraphic Records and Royal Chariots: The palace galleries house rare historical documents that mapped old-world trade and governance. Visitors can view ancient stone inscriptions, copper plates detailing royal grants, and gold coins (Puthens) minted by the Cochin Kingdom. The lower carriage houses showcase impeccably preserved, wood-and-silver royal horse chariots, hand-drawn palanquins, and vintage transport wagons used by European dignitaries visiting the court.

Stroll the Terraced Deer Park and Botanical Grounds: Beyond the structural galleries, the rolling 54-acre estate features vast green spaces designed for leisurely exploration. Visitors can walk along manicured stone steps to visit the peaceful, state-run Deer Park nestled under deep canopy trees. The adjacent botanical gardens house a collection of hundreds of species of rare, native medicinal herbs and ancient trees, providing a refreshing, natural oasis away from the urban bustle of central Kochi.
