 In 1867 the palace was encased in stone for Queen Ranavalona II by Scotsman James Cameron, an artisan missionary of the London Missionary Society.The neighbouring Tranovola, a smaller wooden palace constructed in 1819 by Creole trader Louis Gros for King Radama I, was the first multi-story building with verandas in the Rova.The model offered by Tranovola transformed architecture throughout the highlands over the course of the 19th century, inspiring a widespread shift toward two-storey houses with verandas.
