Holy church of "Koimesis", situated North-East of the municipality of Kalambaka,
was the old cathedral of the Bishopric Stagoi.
The church is a spacious basilica with nave which rises higher than
the two aisles. It was built probably in the 10th or 11th century, on the remains
of an early - christian basilica. Part of the floor mosaic is saved, while material
from the early byzantine ambo has been used to firm the new one of marble, in
the centre of the church. From the old church comes the ciborium of marble and
the synthronon. The wall paintings of the church date from 12th to 17th century.
The monument has been restored and the frescoes (part of them;) conserved.
Nowadays it is used as a church.
