Kariye is located at Edirnekapı section of İstanbul. The dictionary meaning of Kariye (Chora) is "outside of the city", or "rural" in old Greek. The existence of a chapel outside the city walls in very old is mentioned in some sources. The first Khora Church was built on the site of this chapel by Justinianus. The building which managed to survive until the times of the Commenos with various additions and repairs, gained importance when the Imperial Palace Blakhernia near the city walls was expanded. At the end of 11th century Maria Dukaina, the mother-in-law of Emperor Alexi I had it rebuild. The church has a kiborion shaped space whose dome is carried by four arches. During the Latin occupation of 1204 - 1261, both the monastry and the church became extremely run down. During the reign of Andronikos (1282 - 1326), one of the prominent names of the day, the writer, poet and the minister of treasury Theodore Methocite had the monastry and the church repaired towards 1313, and had an annex to the north of the building, an outer narthex to the west and a chapel (Parekklesion) to the south. These new additions were decorated with frescoes and mosaics. Parekklesion, which is a long single naved chappel going along the southern facade, is built above a basement floor. It is partially covered with a dome and the remaining sections are covered by vaults. It has a single abscissa. The outer narthex which runs along the full western facade forms the present facade. The northern wing is only an insignifcant corridor. The central dome has a high drum. It is a Turkish period restoration and is made of wood. Outer facades are given plasticity and movement with round arches, half braces, niches and rows of stone and brick. The eastern facade is finished with abscissa extending to the exterior. The middle abscissa is supported with a half arched brace.
The building was used as a church after the conquest of İstanbul but was converted into a mosque in 1511 by the Visier Grand Hadım Ali Pasha, who later added a school and a alm kitchen next to it. After the conversion, the mosaics and frescoes were covered, sometimes by wooden blinds and sometimes by whitewashing over them. All the mozaics and frescoes were uncovered with the work carried out by the American Institute of Byzantine Research between 1948 - 1958.
Chora mosaics and frescoes are the most beutiful examples of the last period of Byzantine art (14th century). They show a striking similarity. The monotonous background of the former period cannot be seen here. The concept of depth, recognition of the placticity and movement of the figures and the elongation in the figures are the characteristic of this style. Scenes from life of Jesus are given on the outer narthex while the inner narthex has scenes from the life of Madonna.On the portal of the door joining the outer to the inner narthex, there is Christ the "Pantocrator". On the left the scenes depict the birth of Jesus, population cencus being carried out under the supervision of Governor Cyrinus, the angle telling Joseph to leave taking Mary with him, the multiplication of loaves of bread, water turning to wine and on the right side scenes such as messanger kings informing about the birth of Christ, healing of the stroke victims and the massacre of children.
The most beautiful mosaic on the inside is Deisis. There is Jesus in the center with Mary on the left, below Mary, Isaac Commenus and a nun on the right of Jesus. This woman is the daughter of the Mikhael Palaiologos VIII. She was married to the Mongolian Prince Abaka Khan and following her husnband's death returned to İstanbul and became a member of a religious order. In this section, under the dome there is Jesus and his ancestors are shown in the segments. On the portal of the church proper, there is Christ in the middle and on the left Theodoros Metochites who has restored the church and adorned it with the mosaics presenting a model of the church.
The life story of Mary, which is not included in the Bible is taken from subjects based on the Apostles. At the inner narthex the scenes about Mary can be followed depicting her birth, her first steps, Gabriel telling her that she shall have a child, Mary buying wool for the tebernacle and others. Mosaic above the inner portal of the entrance to the main church depicts the death of the Virgin, Madonna bearing the child Jesus and a Saint. Parekklesion is totally decorated with frescoes. The Anastasia (rebirth) scene seen on the abscissa is a masterpiece. The last judgement above it is shown here in full. It is known that the niche on the right and left sides of the parekklesion are graves. On the dome of the Parekklesion there is Marry and the child Jesus and 12 in the segments.
