In the northern part of Persepolis is the ruins of Naqsh-e Rostam.

Four cross tombs are carved high up on the rock wall of Naqsh-e Rostam. The four tombs are said to belong to Darius I, Xerxes I, Artaxerxes I, and Darius II, but it is not clear. The cross is designed with two golden ratios stacked on top of each other.

In Kaabaye Zoroaster near the rock wall, there is a masonry with a notch.

This Kaabaye Zoroaster is also designed with a ratio of two golden ratios.
