Parts of the Church
1 The Church of the Holy Cross
The Holy Cross Church has a four-leaf clover shaped cross plan (tetraconchos) with a central dome. Its exterior dimensions are 16.00m. x 12.50m. When the facades are examined, it is seen that the cross arms on the east and west sides of the structure are built deeper. With the addition of the community hall to the western cross arm in 1763, where the main entrance used to be, this side was covered up to the height of the plastic ornaments. The facade livens up with two 1.10m wide, inward-stepped niches with round arches. There are two rectangular windows with round arches in the middle of the niches. The lower window is aligned with the ornamental border with religious themes and the upper one is below the ornamental border with vines in the background. The upper part of the western cross arm ends with a triangular pediment. There are two rectangular windows on the northern and southern surfaces as well. The entrance door, which is inside the community hall today, is 2.00 m high and 1.36 m wide.
In the southern side of the building is the king’s court. The exterior stairway leading to the gallery was cancelled at the end of the 18th century, when the bell tower was added. The southern wall was built in five facades on the outside. There is a door to the king’s court above the lower entrance which his 1.35m wide and 2.00m high. There are three window openings, one above this door and two on the side walls. These rectangular windows are round-arched.
Eastern side, which has the same structure as the western side, has a straight façade of 9.00m from the outside, including the past ophorion rooms. This straight wall livens up with two vertical 1.10m wide niches, on both sides of the apse. These niches are inward-stepped and round-arched, just like the ones on the western façade. In the middle of the apse and in alignment with the religious-them edornaments, there is a rectangular, round-arched window opening. Two smaller windows are made just below the botanical ornaments. The window on the south is round arched, the one in the north is straight.
In the north of the north niche, there is another tiny grated window. The upper part of the façade ends with a triangular pediment. The northern side of the structure, which is built in five façades from the exterior as the southern façade, is covered up to the ornamental border due to the chapel added in front of the entrance door on an unknown date. The western side of the northern façade can be traced down to the ground level. In alignment with the main ornamental border, there is a rectangular, round-arched window. The façade is ended with a triangular pediment at the top. The arms of the cross on the four façades that form extensions from the central square hall are covered with a double chamfered roof. The sixteen-sided dome trimmer is covered with a pyramidal cone. Between the eight windows placed on the trimmer, there are also six niches in the form of windows. The windows on the trimmer are rectangular with round arches. The tip of the pyramidal cone is slightly damaged. It is seen in the old narrations that there used to be a stone cross on the top of the conical roof. In the inscription on the southern façade, it is stated that the dome collapsed and was repaired; although it is not stated when and by whom the restoration was done, it is a known possibility that it was repaired by Stephanos III in the end of the13th century.
The church is surrounded by a cemetery in the north and southeast. The 0.85m x 1.10m thick walls of the church are mounted on a two-stepped platform. Building walls are laid with red tuff face stones. According to a rumour, the stones used in the building were brought from the province of Aghznikh (a region in the north east of today’s Diyarbakır). The main outer walls of the building are constructed with masonry wall technique, using face stone. Stone material is used in the conical roof of the structure. Such construction method is specific to this region. Aghtamar Church attracts attention for the richness of its exterior reliefs that surround the structure at various levels. Moreover, the interior of the structure is adorned with frescoes.
2 The Chapel
The Chapel of Catholicos I Zacharias is located at the northeast of the church. The chapel has a rectangular plan with dimensions of 6.60m x 4.80m. This structure which was built independently from the church, was later connected to the church with a barrel-vaulted hall of 2.50m x 1.15m.
The western façade of the chapel is covered up to the roof level by a structure (the community hall) that was added in the later periods on an unknown date. This façade has a window opening to the apse.
The northern and the eastern façades of the building are covered almost up to the roof level with soil. The top of the chapel is covered with a double slope roof built from the outside. The entry in the chapel is through a 0.95m wide door on the west side. The door with a pointed-arch pediment is framed with two rows of wooden moulding. The interior is 3.15m x 2.80m and it is covered with barrel vault. The apse on the east with a depth of 2.10m, is 0.80m high from the ground. In the very middle of the apse half circle, there is a grated window with interior dimensions of 0.60 x 0.30m.
The main outer walls of the structure are about 1.00m thick and is constructed within filling masonry technique. Brown smooth face stones are used in the exterior façades and the vaults of the interior. Pitch-faced stones are used for the lower parts of the apse and the interior walls, whereas bricks are used in the middle part of the apse. The facing stones of the upper cover of the chapel fell off. Filling layer made of rubble stones is visible. There are ornamentation elements in the structure.

The passage to the ribbed and low dome with a diameter of 3.55 standing on the piers, is by pendentives. In the interior, the whole cover system except the dome is cross vault. The ones in the east and the west are 1.00m narrower than those in the centre. Entrance to the church is through the east door. The base of the community hall is built1.20m lower than the church floor, so entry to the church is through stairs of four steps.
The main outer walls of the structure are 0.90m x 1.10m thick. It is seen that face stones and rubble stones are irregularly used on the main outer walls.
