Undoubtedly, the mosques are the buildings where decorative stonework embraces a wide area in Ancient Turkish Islamic Arts today as it was in the past. It is possible to see the monumental examples of our stonework on crown gates, mihrabs, minbar (a pulpit in the mosque where the imam stands to deliver sermons), balcony-body connections, fountains, a public fountain, column caps, gathering-place railings, etc. The muqarnas on crown gates and mihrabs is the most important form that reflects the aesthetics of Islam. A muqarnas is an application of converting a geometric design into the third dimension; it serves for multiple purposes such as a load bearer, an ornament, and an element for static and plastic deformation. Based on the variations attempted in many cases, muqarnas craftsmanship offers features that give the building an identity that dates the building on which it is located. Muqarnas, the main material of which is stone and marble, finds its place not only in crown gates and mihrabs but also as a superior form in minaret corbels. Today, in Turkey, the stonework is supported by technology as well as traditional carving techniques. CNC 3D marble and granite processing machines can give the desired form to the stone. Teknom Yapı becomes a partner in the artist’s struggle for existence to achieve the deserved position of traditional handicrafts in our country by using all the elements related to art in building Islamic places of worship. There are traces of ancient arts on stone elements used interior and exterior of the place of worship, minaret, and courtyard. Teknom Yapı, which uses stone elements, especially marble, in almost all its projects, has many names of the masters in stone and marble works in its inventory. There are marble and stonework masters from all over Anatolia who perform their arts handed from father to son, who keep pace with technology and open to innovation. The close relationship between Teknom Yapı and these masters is not only business-oriented. Teknom Yapı is in collaboration with these masters in many ways, such as improving art, material supply, and quality, applied patterns, and expanding the form repertoire.
