The columned porch, or talar, seen in the rock-cut tombs near Persepolis, reappear in Sassanid temples, and in late Islamic times it was used as the portico of a palace or mosque, and adapted even to the architecture of roadside tea-houses. Similarly, the dome on four arches, so characteristic of Sassanid times, is a still to be found in many cemeteries and Imamzadehs across Iran today. The notion of earthly towers reaching up toward the sky to mingle with the divine towers of heaven lasted into the 19th century, while the interior court and pool, the angled entrance and extensive decoration are ancient, but still common, features of Iranian architecture.
