Llangiwg Church is an Anglican parish church with medieval origins, significantly altered in 1812. Nestled in one of the more remote and picturesque areas of Glamorgan, the church holds considerable historical importance, preserving much of its medieval fabric despite its isolated location. For centuries, it served as a spiritual and community hub for Llangiwg and its surroundings, retaining its status even after being declared redundant in 2004. Today, it is cared for by The Friends of Llangiwg Church.

Historically part of the Lordship of Gower, Llangiwg Church was a notable destination for pilgrims during the late medieval period. The site is steeped in history, encompassing the church itself, its churchyard, a well, and possibly an early Christian platform. Like many ancient rural churches, Llangiwg faced challenges over time, particularly as societal shifts and modernization led to declining congregations. By the 19th century, the church had fallen into disrepair, with its community dwindling as people moved to urban centers or larger, more modern places of worship. Eventually, the building was abandoned, and regular services ceased.

In recent decades, however, growing interest in preserving Welsh heritage has sparked efforts to restore Llangiwg Church. The establishment of the Llangiwg Church Trust marked a turning point in protecting and maintaining the site. Through the dedication of local historians, volunteers, and conservationists, the church has been stabilized and partially restored, ensuring its historical and cultural significance endures. Today, visitors are welcomed to explore this remarkable site, which stands as a testament to the legacy of Saint Ciwg and the rich history of the region.
