The «Unfinished Gate» and the «Archive»
The «Unfinished Gate» and the «Archive» area. The former was intended to be a larger copy of the Gate of All Lands, and was to link the latter structure to the Hundred Column Hall via the «Army Street». Its construction however, was never completed, probably due to the invasion of the Macedonians.
Other Remains
To the east of the Hundred Column Hall was a building consisting of a vestibule and several chambers and porticos, and further north were a columned hall, several chambers, and storage rooms. These were in all probability built for the men-in-arms.
The Stone Well
Parallel to the northeastern corner of the Treasury, and 22m higher than its level, a deep well was cut into the rock of the Royal Hill. It has a depth of 26 meters and an opening measuring 4.70x4.70 meters. It was linked to a large moat which took the rainwater from the hill to the plain below the Terrace.
The Treasury
The fabled Treasury of Persepolis stood south of the Hundred Column Hall and east of the main wing of the Harem. It was constructed in several stages. One of the earliest buildings to have been built on the Terrace, the original Treasury measured 120x60m, and its long axis was aligned in a west-east orientation.
The "Tripylon" or "Central Palace"
The center of Persepolis is occupied by the remains of a fairly small palace which is linked by means of three doorways and several passages to various other palaces. Hence, it is referred to as the «Central Palace», or often, as the «Tripylon» and less frequently, as the «King’s Gate».
The «Palace G»
In the middle of Persepolis there is a rocky platform between the Apadana, the Tachara, the northern courtyard of the Hadish, and the Tripylon. A structure had once stood on this platform, but today only scattered remnants of it are seen. The original building has been named "Palace G ".
The «Gate of All Lands»
This was a four-pillared hall constructed to the east of the landing place and some 22m away from the edge of the platform. Iranian dignitaries and representatives of other nations passed through this hall in order to be led to the Audience Palaces (the Apadana and the Hundred Column Hall) on the Terrace.
The Service Entrance
Apart from the grand staircase, another entrance to the Terrace is known, which due to its remote and inconspicuous location could have served only as a service-gate. This was a small door situated near the northwestern corner of the platform where the rock was not hewn;
The Terrace Stairway
The Terrace of Persepolis is ascended by means of a grand double-flighted staircase situated towards the northwest corner of the platform. Here, just in front of the platform, and adjoining the terrace wall is an area measuring 10.5x7 meters, which is paved with huge well-polished blocks of gray limestone.
The Hadish or "The Palace of Xerxes "
The palace which Xerxes built as his private residence on the terrace is twice the size of the Tachara of Darius, and is usually called the Hadish because it is so called in one of its inscriptions. It stood on a platform hewn from the natural bedrock 18m higher than the level of the plain and was ascended by four staircases: one from the Tachara courtyard, another from the court south of the Tripylon, and the remaining two from the west wing of the Harem.
