Gower: Llanmadoc and Llanddewi

The parishes of Llanmadoc and Llanddewi sit between the Burry Estuary salt marshes and the rising Gower hinterland in a remote corner of that Marcher lordship. Here the Order of the Hospital of St John of Jerusalem established a significant Welsh holding, surpassed only by their Pembrokeshire lands. These estates comprised cohesive manorial units rather than scattered tithe parcels. They dictated the social and economic rhythms of this coastline for several centuries. Readers of Welsh history often associate military orders in such locations with the Knights Templar. However, the physical and documentary evidence points consistently to the white cross of the Hospital. There is no proof of the red cross of the Temple here. These two manors were Hospitaller foundations from their start through to their final dissolution in the sixteenth century.

Historical confusion about these sites stems from nineteenth-century antiquarians. The Templars were suppressed with institutional violence in 1308. Local legends subsequently filled this vacuum by attributing any medieval building of military or monastic appearance to the 'Red Knights'. Systematic archival research by William Rees and Helen Nicholson has corrected this error. Charter evidence and later surveys confirm the Gower estates were never Templar property. The early Marcher families, specifically the de Newburghs who were Earls of Warwick, granted these lands directly to the Hospitallers. They were part of the administrative network managed by the commandery at Slebech long before the Templars were arrested and their Order destroyed. This distinction clarifies the actual geography of the military orders in Wales. The Hospitallers acted as independent landowners from the late twelfth century. They were active managers of their own territory, not people who simply moved into empty Templar ruins after the trials ended.

The 1338 survey, written by Prior Philip de Thame and edited by Larking in 1857, offers the most detailed view of these holdings. When this report reached the Grand Master in Rhodes, it described Llanmadoc as a functioning manor. The text identifies it as a membrum of Slebech, containing a manor house, two carucates of land, and a watermill. The document lists the redditus assisae—the fixed rents paid by free tenants—beside the financial values of the mountain pastures. These acres were prized for their connectivity in the fourteenth century. From Llanmadoc hill, the Hospitallers watched the shipping lanes of the Bristol Channel. This geography allowed them to ship Gower grain and wool to markets in Bristol. These profits eventually moved further east to support the Order's military and medical commitments in the Mediterranean theater.

Llanddewi parish sits slightly inland and provided a different landscape for the Order. Llanmadoc was positioned between the sea and the soil, but Llanddewi offered sheltered grazing and light arable land. The church of St David stood as a sign of the Order’s spiritual patronage over the local tenants. In the medieval period, the Hospital cross represented a legal and religious reality rather than a distant crusading ideal. The Hospitallers held the right of advowson, which meant they appointed the parish priest. They also paid for the maintenance of the chancel. This role as both landlord and spiritual protector gave the Order significant local influence. Inhabitants of Llanddewi likely saw themselves as part of a European network. Their daily farming and labour helped fund the defence of the Krak des Chevaliers or the hospitals in Acre and Rhodes.

Archaeological evidence of the Hospitallers in Gower is quiet and domestic. The Order did not build great stone fortresses here because they were not in constant conflict with the native Welsh. They were managers of a stable, colonial landscape. Ruins near the church at Llanddewi are often called the manor house or a grange. These remains might include later masonry, but they sit on the foundations of the administrative centre described in the 1338 survey. This hub was where the bailiff collected rents and where the local manorial court held its sessions. The buildings were functional rather than grand. They consisted of sturdy stone walls, timber roofs, and granaries for storing the tithe. Such structures reflect the needs of a working estate rather than the monumental architecture found at a major continental commandery.

The Gower estates show the strategic patience of the Order of St John. Many small, fragmented grants in the Welsh interior were lost to political shifts or local friction, but the Gower block remained a stable asset for centuries. It survived the plague of the mid-fourteenth century and the economic changes of the 1400s. The land stayed under the control of Slebech until the Dissolution in the sixteenth century. The Knights eventually lost the land to secular gentry families like the Mansels. Despite this, the parish boundary lines still follow the ancient Hospitaller map. These Gower hills show how a knightly order, which began in a Jerusalem infirmary, established a permanent home on the western fringes of the March. The landscape retains the shape given to it by these medieval administrators over four hundred years of continuous tenure.

Cross-reference: The Gower holdings are covered in more detail in Chapter 9, see §1 The Western Finger of Gower, §2 The Southern Chain: Rhossili and Port Eynon and §3 The Exempt Parish.

These manors stayed in the Order's possession until an Act of Parliament ended the monastic system in Wales.
