According to some studies carried out on site, especially on the chronology of the building, the construction of the church could not have been earlier than the second half of the 16th century. Traces of these 16th-century works are in fact still visible in some parts of the main building, which instead dates from the 18th century.
The first written mention of the church dates back to 1506, even though the church is only shown on maps from the end of the 16th century. According to the documents of the notary Vincenzo Molfino found by the historian Arturo Ferretto, a document dated July 10, 1516 from the vicar of the archbishopric of Genoa testifies to the construction of the chapel dedicated to Sant'Anna thanks to the alms given by the pious during the daily masses Wives of the local Musso, Oxio and Morinello families were collected. The church is also mentioned in a 1537 document by the Genoese chronicler Agostino Giustiniani.
A religious cult for the saint and consequently for the building, further commemorated by a decree of July 23, 1578 of the Bishop of Brugnato, Monsignor Antonio Pagliettino, and the Podestà of Sestri Levante, Donato Bogiano; a festival officially declared a popular festival for nine days in 1647 by an act of the Senate of the Republic of Genoa.
On August 31, 1673, during a pastoral visit, Monsignor Giovanni Battista Da Dieci ordered some minor work to be done on the sacristy and the bell tower of the church. On the other hand, the works commissioned in the 18th century were larger and more demanding, as evidenced by a public auction held on November 5, 1727, and the work being awarded to a local mason on August 6, 1728.
The church almost certainly fell out of office from 1810, after some places of worship were closed and religious orders suppressed by the new pro-French administration of the Apennine department (First French Empire). The subsequent opening of the new Napoleonic coastal road under today's coastal section of the state road 1 Via Aurelia - an unstoppable and rapid abandonment of the historical path and thus also of the church decided; The latter had already partially collapsed in 1820.
