Dassa-Zoumè
A town among granite hills in central Benin, and the country's main Marian pilgrimage site.
Updated 16 October 2026
Dassa-Zoumè sits among a cluster of granite domes in central Benin, the town built between and around them, and a grotto on one of the hills has become the country's principal Marian shrine, drawing tens of thousands of pilgrims each August for a gathering that fills the town completely. A royal palace and court also function there, and the hills themselves carry caves that were used as refuges.
Background
Other names for the town are Igbó Ìdàáshà and Dassa, and it is the capital of the Collines Department. It stands on the railway from Cotonou to Parakou and on the main north-south highway. The commune covers 1,711 square kilometres and had 112,118 inhabitants in 2013. Its founders came from the Egba people around the 12th century, and the Idaasha are the indigenous population. A kingdom of Dassa was founded around 1600, and a Yoruba constituent monarchy has its seat here. The Marian grotto is the Grotte Notre-Dame d'Arigbo, now enclosed by a basilica with several shrines. Many of the surrounding hills and forests hold Orisa shrines.

When to go
