The design feature of Hagia Sophia that is considered the most daring is the main dome encircled by a band of forty windows.

Explanation

Hagia Sophia is consideed by  many as the masterpeice of Bryzantine architecture and it is located in Turkey. The daring feature of the masterpeice is doubtlessly the central dome which is 184 feet high and has a diameter 102 feet. The very fact that the huge dome sits on pendentives and not on a flat solid base makes the structure a daring one.

Pendentives are supporting arches at square corners makes a circular plan possible. The main dome can be called a succession of smaller domes because the arches at east and west are extended by half domes that rest on even smaller portecos.
