It is one of the oldest temples in Veria with plentiful painted decoration dated back to the centuries 14th, 16th and 18th century. The original temple dates back to the beginning of the 14th century. It is a representative sample of a single spaced temple of basilica with wooden semi rising alcove but its form changed dramatically in the 16th century after substantial interventions on the northern and western wall.
At the original section of the temple which is preserved until now a lot of beautiful frescos are maintained dating back to the year 1320, which among others are the icons of the full-figured Holy Virgin carrying baby Jesus along with two angels bending themselves as a gesture of worship and devotion, the Annunciation, the Ascension, the Nativity, the Candlemas as well as the full-figured icon of Saint Vlasios which is the honored Saint. There are also depictions of Saint Vlasios life which are dated back to the 14th century.
