The numerous churches and monasteries of Sifnos are closely
linked to the history, architectural tradition and social
and religious life of the island.
From a historical point of view, the Sifniots took advantage
of the privileges granted to them by the Turkish sultans in terms  of religious freedom.
Thus in 1646 the Archbishopric of Sifnos was founded which,
in addition to Sifnos, included the islands of Amorgos, Anafi,
Astypalaia, Iraklia, los, Mykonos, Serifos, Sikinos and Folegandros.
Subsequently, the Sifniots got into the habit of bequeathing their
property to churches and monasteries and taking charge of various
obligations, such as the celebration of ceremonies (mainly festivals).

Many of the churches and monasteries of Sifnos are classified as historical monuments and are of great religious and architectural interest. Ecclesiastical committees and “fraternities” are responsible for their maintenance, with admirable perseverance and often voluntary work, although some of these buildings are often located in places inaccessible to motorized vehicles.
The number of churches and monasteries that exist in Sifnos testifies to the religious tradition of the inhabitants. Compared to the total area of ​​the island, this number of 237 is the highest in all the Cyclades.
