Our Lady of Lourdes Grotto is a stone shrine at the White Fathers' Mission in Navrongo, in the Kassena-Nankana Municipal District of Ghana's Upper East Region. It stands within the mission and cathedral site, which also contains accommodation facilities. The grotto takes the form of a stone shrine with an altar and a statue of the Madonna.
The shrine was built by Father Robert in 1933–34, at the same time as the first Bishop's residence. Stones for its construction were carried from Pungu and Nayaginia, so the structure is tied both to the mission's early building programme and to the surrounding communities that supplied its material.
The grotto's documented history extends beyond its construction. A gelatin silver photographic print of the grotto dated 27 February 1936, taken by Mary S R Sinclair, is held by the British Museum (object EA Af-A14-5), where it is catalogued as showing a stone shrine with an altar and a statue of the Madonna at Navrongo. That record makes the shrine one of the more precisely dated early mission structures in northern Ghana.
Navrongo itself is a market town adjacent to the Burkina Faso border, at approximately 10°53'5"N 1°5'25"W. Visitors travelling in the Upper East Region will find the grotto on the same site as the cathedral, which places it within an active religious and institutional complex rather than a standalone monument.
Because the grotto is a place of worship on a working mission site, visitors should expect to encounter it as such. Practical details — opening times, whether access is possible during services, any fees, and how to arrange a visit — are not established by the available sources and should be confirmed locally before travelling. The evidence also does not describe the current condition of the shrine, its setting, or facilities for visitors, so those points remain unknown.
