A rova is a fortified royal complex built in the central highlands of Madagascar by Merina of the Andriana (noble) class. The first rova was established at Alasora by king Andriamanelo around 1540 to protect his residence throughout a war with the neighboring Vazimba. Rovas are organized according to traditional symbolic notions of space and enclose the royal residences, the tomb of the founder, and a town square marked with a stone. They are protected with walls, trenches and stone gateways and are planted with fig trees symbolic of royalty.

The Kingdom of Merina, or Kingdom of Madagascar, officially the Kingdom of Imerina, was a pre-colonial state off the coast of Southeast Africa that, by the 18th century, dominated most of what is now Madagascar. It spread outward from Imerina, the Central Highlands region primarily inhabited by the Merina ethnic group with a spiritual capital at Ambohimanga and a political capital 24 km (15 mi) west at Antananarivo, currently the seat of government for the modern state of Madagascar. The Merina kings and queens who ruled over greater Madagascar in the 19th century were the descendants of a long line of hereditary Merina royalty originating with Andriamanelo, who is traditionally credited with founding Imerina in 1540.
