Mahandrihono Palace
The Madagascar king built the Mahandrihono palace, which was intended for his children. Within the Palace's stone walls are numerous other modest houses where each of the king's children used to live so that he could readily oversee them and prevent a coup against his realm.
The monarch was a polygamous guy with a large family, which is why he built the Mahandrihono Palace so that all of his children could dwell in the same compound and be readily watched.
