How were medieval lighthouses funded?

 title: 'A coin with a lighthouse depicted on it.'

Marking dangerous reefs and leading mariners safely into port were formerly the work of Christian charity[1]. Bells on rocks, marks on shoals and sands, and beacon lights used to be maintained by the great monasteries, or by their various offshoots, in this country[1]. It confiscated the property from the profits of which such lights had been maintained[1].

After the religious changes, those engaged in navigation, no longer able to get what was needed as charity, seemed, after awhile, to have suggested paying for it[1]. One of the earliest post-reformation lighthouses suggested was that at Winterton, for which proposals were heard in 1585[1].
