The Eastern Orthodox Keras Kardiotissas is dedicated to Virgin Mary that is situated near the village of Kera of the Heraklion regional unit in Crete. It is built on the north slopes of Mt. Dikti, at an altitude of 650 m and a location that is approximately 50 km east of Heraklion, next to the road to Lasithi Plateau.
The exact date of the monastery's establishment is unknown. However, references to it are made in manuscripts dating from the early fourteenth century. The monastery was named after an old icon of Theotokos that according to tradition was miraculous. That icon was stolen in 1498 by a wine merchant and transferred to Rome where it is now permanently enshrined in the Church of St. Alphonsus near the Esquiline Hill. The stolen icon was replaced by another one in 1735 that is also regarded as miraculous. During the Ottoman occupation of Crete, the monastery often served as a local revolutionary center and suffered several retaliatory attacks as a result. In 1720, Kera monastery became Stauropegic (independent of the local Bishop).
The monastery is surrounded by fortified walls. The main church (katholikon) was originally built as an arch-covered single space structure and was later expanded with two narthexes and a smaller chapel. The church features murals dating to the 14th and 15th centuries.
Today, the monastery functions as a nunnery. It celebrates the birth of Mary on September 8th every year.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
