Sacred hills of Imerina

The twelve sacred hills of Imerina are hills of historical significance to the Merina people of Madagascar. Located throughout Imerina, the central area of the highlands of Madagascar, the sites were often ancient capitals, the birthplaces of key public figures, or the tomb sites of esteemed political or spiritual leaders. The first set of sacred sites was designated by early 17th-century king Andrianjaka. The notion was re-sanctified under late 18th-century king Andrianampoinimerina, who replaced several of the earlier sites with new ones. More than 12 sites were thus designated as sacred over time, although the notion of twelve sacred hills was perpetuated because of the significance of the number 12 in Malagasy cosmology. Today, little concrete evidence of the former importance of many of these sites remains, but the significant archeological and cultural heritage of several of the sites has been preserved. The historic significance of the sites is best represented by the Rova of Antananarivo at Analamanga, the ancient fortified city at Alasora, the houses and tombs of the andriana (noble class) at Antsahadinta and the ancient fortifications and palaces at Ambohimanga, protected as a UNESCO World Heritage Site since 2001.


According to popular legend, King Andrianjaka (1610–1630) declared twelve hills in Imerina (the central region of the Highlands of Madagascar) to be sacred due to their historical, political or spiritual significance to the Merina people. King Andrianampoinimerina (1787–1810) designated twelve hills in his turn, including several of those first identified by Andrianjaka. Most of these hills served as locations of the capitals of rival kingdoms conquered by Andrianampoinimerina and united under his rule, and many are also the seat of power of historic kings and queens of the Merina dynasty.

Key sitesEdit

Twelve is a sacred number in Merina cosmology and it is commonly said that Andrianampoinimerina had twelve wives and installed one on each of the twelve sacred hills throughout his kingdom.[1] In reality, he had more than twelve wives, and there are more than twelve hills surrounding Antananarivo that claim sacred status.[2] As such, precisely which hills should constitute the list of twelve sacred sites named by Andrianampoinimerina remains a point of some contention,[3] but diverse sources have commonly indicated the following sites:

Hill of AlasoraEdit

Alasora, 2013

Alasora[1][2][4][5][6] 1348 m, latitude 18°57'46.08"S, longitude 47° 34'09.74"E.(15 km northeast of Antananarivo) Alasora is one of the oldest villages in Imerina, believed to have been founded by Prince Ramasimparihy in 1490. Ruling from Imerimanjaka, vazimba Queen Rangita (1500–1520) and her brother Andrianamponga gave the site its current name. Under Rangita's daughter, Queen Rafohy (1520–1540), the capital of the region was moved from Imerimanjaka to Alasora. Some of the monumental features of the site were added upon the orders of her son, King Andriamanelo (1540–1575), including the hadivory and hadifetsy (defensive trenches around the town), as well as the vavahady, a town gate protected by a large rolled stone disc acting as a barrier and shaded by aviavy (fig trees), symbolic of royalty. This town model was subsequently adopted throughout Imerina. Andriamanelo's tomb is located here.[7]

Hill of AmbohidrabibyEdit

Ambohidrabiby (or Ambohitrabiby)[1][2][4][5][6] (20 km north of Antananarivo): Site of the capital of King Ralambo (1575–1610), who is buried here, along with his Vazimba grandfather (or father-in-law) Rabiby, a renowned astrologer for whom the hill is named.

Named for King Ratrimo who, in the mid-12th century, was according to oral history the first king to have established rule over the territory. After several unsuccessful attempts to capture the hill by force, Andrianampoinimerina finally managed to successfully incorporate the territory into his kingdom by marriage with his first wife, Rambolamasoandro, princess of Ambohidratrimo and eventual mother of his son and successor Radama I.[8]
