The 4-meter high monument's interior, erected on a concrete base of 2 meters diameter, was covered with İznik tiles featuring slow-swaying tulip motifs. These motifs were first used in 1561 at the mosque built by Suleiman the Magnificent's son in law Rüstem Paşa in Istanbul. The cobalt blue, red and turquoise colors of the tulips form a true color burst, and the tiles scaled to emphasize the vertical axis make it easier to guide the eye onto the celestial sky. When the darkness falls, a strong light rising from the ground illuminates the interior covered with tiles, creating a bright triangulation point. Architect Han Tümertekin who designed the monument, says that the monument's identity focusing on the interior serves as a peaceful haven, away from Tokyo's hectic daily life.
