in small garden plots. Owners of these plots would descend the cliff-face between the months of March and April to cultivate the land and return in September for the harvest. For efficiency, they pressed the wine grapes in the fajã using rudimentary stone presses: liquid wine in jugs is easier to transport than fragile and perishable grapes. On the fajã is a cave locally called ''Furna'' ("

. Following a 1 January 1980 earthquake, the debris field began eroding away. After the earthquake access to the fajã was restricted due to its instability, resulting in the temporary closure of the lighthouse of Ponta dos Rosais. By 2012 the fajã was reduced in size so significantly it may be considered to no longer exist.
