The Dome of Chain (Qubat es-Silsila), a domed hexagon with open arches, is adjacent to the eastern gate of the Dome of Rock, and marks the exact centre of the temple mount. It is the only structure on the east side of the raised platform.
This is the Dome of the Ascension (Qubbat al-Miraj). It was initially a Crusader baptismal, then destroyed and rebuilt as a Muslim shrine (1200) to commemorate the location of the site where Prophet Muhammad prayed before his ascension to the heavens (622AD).
