Ismail Hakkı Uzunçarşılı wrote that there were two foundations dated 1426/27 of Arslan Bey, Çelebi Mehmet and II. It is understood that he is from Murat ricalin, his brother was a meftun in Tavşanlı in Tokat, and the family's lineage, whose works are also found on the Geyve and Tokat sides, dates back to the statesmen of the Seljuk period. The mosque is a square-planned, single-domed building made of cut stone and brick. In front of it is the last communion place with three sections. A minaret has also been placed at the corner of the wall separating the main place and the last community place in the west. The facade of the last congregation place rises in the form of a light shield wall. Along with the dome pulley, two rows of hedgehog eaves go around the roof level. A striking point in the external appearance of the mosque is the wide arch openings to the east and west of the square-planned main space. This is an Octagonal planned additional section added by expanding the wide window openings and turning them into a transition. There are narrow and long windows in the middle of this arch. The windows are arched. The transition to the main dome was provided with Turkish triangles, and the transition to the domes at the last community site was provided with mukarnas fillings. The mihrab niche Aproned with eyebrow arch is filled with muqarnas. Pencil work decorations are seen on the ceiling. Meydan Mosque, located at Pafta 14, Ada 81, Parcel 1 in the Central Square neighborhood of Kütahya, belongs to the General Directorate of Foundations and the restoration project was carried out by our company.
