 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.The Rova grounds also contained a cross-shaped wooden house (Manampisoa) built as the private residence of Queen Rasoherina, a stone Protestant chapel (Fiangonana), nine royal tombs, and a number of named wooden houses built in the traditional style reserved for the "andriana" (nobles) in Imerina.
