The Monastery of the Annunciation or the Evangelistria, as it is widely known, is one of the most remarkable monuments of Northern Sporades.< br>
The Monastery was built on the Agallianou site, where there were ruins of an old monastery. The complex was built from 1794 to 1806 and became the stronghold of "Kollyvades". A group of monks from Agion Oros, led by Niphon, due to a feud that emerged after the mid-18th century to the beginning of the 19th, left from there and went to several islands ( Patmos, Samos, Leipso etc.). After a short wandering they went to Skiathos, where they proceeded with the monastery’s building.
Monastery’s architecture is based on the one of the Agion Oros monasteries. The Cathedral is a condensed form of the Athonite type with the lateral spaces, the frugal and the splint and roofed by three domes, covered by gray slates. The rich rood screen projects into the simple space of the church. Only the Holy Step has frescoes from the time of the Greek Revolution, by painters from Galatista. In this space kept in ambries bones of many Saints. Outside the Catholic, within the monastery complex are the monks’ cells, the bank, the hospital, the hostel, the vesta (kitchen), the magkipeio, the taliagkra (olive press), the library, the chapels, the storerooms, the stable, etc. In addition, the monastery has a valuable library with many rare publications and documents, an eccestiastic museum, where are many priestly utensils and relics and a olive press/exhibition.
