 The basic layout of the compound remained largely unaltered from its original design with the sole exception of an expansion of the Rova along its north-south axis.Stone walls topped with sharpened wooden stakes were built around the new perimeter during this period.Venerable buildings such as Besakana, Nanjakana, Mahitsy and Manjakamiadana were retained, as were the houses of several of Andrianampoinimerina's wives, many of whom were still living at the time of Radama's death in 1828.
