 Among the most significant of these were Besakana, erected in the early 17th century by Andrianjaka and considered the throne of the kingdom, and Mahitsielafanjaka, a later building which came to represent the seat of ancestral spiritual authority at the Rova.A fire on the night of 6 November 1995 destroyed or damaged all the structures within the Rova complex shortly before it was due to be inscribed on the list of UNESCO World Heritage Sites.Although officially declared an accident, rumours persist that politically motivated arson may have been the actual cause of the fire.
