Alâeddîn Mosque, the earliest building built in the Seljuk capital, reflects the historical phases of a building whose first construction was probably the "SarayMasjid" and transformed into the city's Grand Mosque over time. However, the linguistic buildings of the Seljuk Palace, which is understood to be a magnificent collection of structures built on a mound known as "AlaeddinHill" and in gardens, disappeared over time by turning into ruins; Due to destruction, abuse, and bad repairs, the physical environment, which contains the material images of the Seljuk period, has changed extraordinarily. The most important work remaining on the hill is this mosque.
The sources record that Aladdin Hill, one of the rare hills in the Konya plain, is a mound built with molds' soil. After taking Konya from the Byzantines and making it the capital, Anatolian Seljuks built the palace (Seljuk Palace) and Alaeddin Mosque on this hill surrounded by a castle. Today, there is a small piece on the hill that carries the palace's memory in question. Alâeddin Mosque preserves its glory as a Seljuk jewel.
Evliya Çelebi's "Itis a beautiful mosque that cannot be explained in languages and cannot be written with pencils." Alâeddin Mosque, which he called it, is one of the early Seljuk works dating to the mid-12th century. However, the mosque was built in several phases. It is possible to understand this from the irregularity in its plan, the use of different building materials, and its inscriptions.
Alâeddin Mosque, which resembles a miniature place when viewed from the north from the Karatay Madrasa, is the integrity of structures consisting of worship, tombs, and a courtyard. However, the mosque (place of worship) at the center of such unity is an obvious disorder in the plan. This irregularity shows itself in the fact that the mosque consists of three separate sections with different characteristics.
The presence of different materials is also considered related to the construction process of the Alaeddin Mosque. Various architectural pieces belonging to previous periods, such as Ancient Ageinscriptions and Greek writings, are among them. The marble columns supporting the arches carrying the top cover in the mosque and their capitals are re-used. The characteristics of the columns used in the mosque also show different characteristics. For example, there are different column type carriers in three units of the mosque as "double," "single," and"knotted." On the mosque's exterior, the piers separating the arch openings on the west-facing walls are spolia.
