In early times, marking dangerous reefs and guiding mariners safely into port was primarily the work of Christian charity[1]. These charitable acts were among the many useful roles that the Church fulfilled when no one else was available to carry them out[1]. Bells on rocks, marks on shoals and sands, and beacon lights were maintained by the great monasteries or their offshoots in England[1]. These beacon lights, though dim and uncertain, were the direct ancestors of the modern lighthouse[1]. This system of using lights to warn mariners existed long before Christianity, with civilizations such as the Lybians, Cushites, Romans, Greeks, and Phoenicians employing similar methods[1].
Ancient civilizations protected navigation through lighthouses, which were high columns with fires of wood in open grates or lamps lit by oil placed on their summits[1]. These structures were similar in style, though smaller in scale, to the tower of white marble erected at Alexandria by Ptolemy Philadelphus[1]. This tower, built nearly three centuries before Christ, cost around £170,000 of our money[1]. Despite differing opinions on who financed this project, evidence points to Ptolemy as its projector[1]. The architect, Sostratos of Guidos, inscribed his name on the tower but concealed it under a layer of cement, desiring perpetual recognition[1]. Time revealed his inscription, acknowledging his skill in benefiting sailors and travelers[1].

While the concept of warning signals predates Christianity, the focus shifts to England, where there is little evidence of lighthouses before the Roman occupation[1]. Following the decline of Roman power, lighthouses likely fell into ruin and were not revived until Christianity firmly established itself, teaching charity toward fellow men[1]. By the 14th century, monks and hermits in England and other maritime parts of Europe warned mariners of dangers around monasteries or hermitages using lights maintained during darkness[1].
On the largest of the Ecrehou rocks, a hermitage or priory existed in 1309, served from the Norman abbey of Val Richer[1]. Land in Jersey supported two monks who sang masses for shipwrecked souls and kindled a bright light nightly[1]. Ruined chapels on rocky crags or headlands likely served as lighthouses for mariners of old[1]. The maintenance of sea lights was a religious office in medieval England[1]. From the hermitage chapel on Chale Down, a light had been kept nightly by monks for over five hundred years[1]. In 1427, a hermit at Ravenspurn built a lighthouse to warn vessels entering the Humber[1]. Additionally, the priests of St. Nicholas chapel in Ilfracombe maintained a fire of wood throughout the winter, guiding ships into port[1].

In one instance, coast lighting was performed by a religious guild, the Brethren of the Blessed Trinity of Newcastle-upon-Tyne[1]. In 1537, Henry VIII entrusted this guild with the navigation of the Tyne, including building and maintaining two towers with lights[1]. Prior to the religious changes in Henry VIII’s reign, coast lighting was a work of Christian charity[1]. Traditions associate towers or steeples of parish churches on the coast with having once been lighthouses, such as Blakeney in Norfolk and Boston[1]. The dissolution of the monasteries swept away the men who tended these coast lights and confiscated the property that maintained them[1]. Leland found few coast lights remaining after the dissolution[1].
The coast was well lit prior to the dissolution, with lighthouses of some kind not uncommon[1]. The writer of The Pilgrimage of Perfection in 1526 speaks of the beacon directing the mariner to port, suggesting the importance of these lights[1]. After the dissolution, most of these lights were extinguished[1]. The lack of lighthouses was keenly felt by sailors who then began to pay for the service[1]. One of the earliest post-reformation lighthouses suggested was that at Winterton in 1585, proposed to be maintained upon the steeple and supported by contributions[1].
