Kornjan Tangkrisanakajorn Historic hill to see from the colonial time. The palace is quite small but offers great view overlooking Antananarivo.
CK Cheong A UNESCO Heritage Site. Comprises a royal city and burial site, and an ensemble of sacred places. The Royal Hill was the burial ground for its sovereigns; built in the 15th century and was set up as a fortified political capital and royal palace during the reign of King Andriantsimitoviaminandriana in the 18th century.
Colleen Zematis A surprisingly simple Palace, in tact from before the French Colonozation and thankfully kept. UNESCO sites are always great. No pics allowed inside buildings
Irina Sonich A must visit if you are near the capital. UNESCO heritage protected. Traditional kings building next to more modern (18c) queens palace. Still favourite with the followers of the old traditional religion where one wants to talk to ancestors and offer a sacrifice! Amazing experience. The entry gate to the sacred hill is worth a visit too
Berfin Karaman It is a UNESCO world heritage. It is the king's palace from 1800s and has queen's summer house from 1900s. The summer house has gifts from different countries such as mirrors from Queen Victoria of England, french cristal ware and wallpaper from Japan. The ticket for foreigners costs 10000 and for local costs 400. I recommend visiting the place with a guide as there are not many written explanation. Has nice panoramik view at the top.
