Pyraeum
From BiblePortal Wikipedia
Pyraeum [1]
a fire temple of the ancient Persians. It was simply an enclosure, in the centre of which was placed the sacred fire, and the building was so constructed that the rays of the sun could not fall on this fire. The first pyrmeum was built by Zoroaster, at Balk, in Persia; and thence the sacred fire was conveyed to other fire-temples both in Persia and India. (See Zoroaster Parseesk).
