The verses outside are engraved into the stone, in large legible letters. Above the doors are small engraved versions of the "Greatest Name", one of several Bahá'í symbols and an elaborate decorative design that includes the letters ABHA, representing the prayer "Alláh u Abhá" (God is Most Glorious) in Arabic. It is the numerical value of these four letters in the words abha and baha (for Baháʼu'lláh) that add up to total nine, one of reasons Bahá'í Houses of Worship are nine-sided.
