A bazaar was discovered, with alleys and pavements opening onto small baked brick shops. The first phases of the bazaar are probably related to the last period of the Habbārid emirate (late 10th cent. AD to 416 H/1025 AD). The later phases possibly correspond to the period of the Ghaznavid and then Ghūrid sultanates (c.1050-1220). A commercial note in arabic (fig. 4) and some ceramic kiln utensils were discovered in those stratigrafic layers (fig. 5). The ceramic material found shows that this is the richest period of the site (fig. 6). Red ware remains the most common type (about 66% of the material) and is mostly decorated with painted decoration (about 38%). The material is also characterised by the very clear increase of two more luxurious ceramic types: grey or black fabric ceramics (14.3% of the material) and glazed wares (fig. 7), probably of local manufacture (19.2%). The glazed ceramics are mainly bowls and dishes, whose surface ornament is very similar to contemporary Khurāsān productions. They are also similar to those found at Banbhore and al-Manṣūra.

The baked brick structures uncovered in these layers were probably dwellings reserved for the army. Some traces of iron metallurgy were also found. The important testimony of Ibn Baṭṭūṭa who visited Sehwān around 734/1333-1334 confirms the presence of a large garrison quartered in the fort, which was partly reconstructed. The first period of this Phase can be dated to the 13th-14th cent. AD and is related to the period of the Delhi Sultanates The second period is possibly related to the regional Sammās dynasty in the 15th cent. AD. The change in status of the site from fortified city to military stronghold is linked to important changes in the ceramic material (fig. 8). The most sophisticated types, grey and black ceramics and glazed ceramics, are much less frequent and their quantity progressively decreases until they almost disappear at the end of this period.

A black layer of destruction seals the previous Phase, possibly related to the taking of the fort by Shāh Beg Arghūn in 928/1521-1522. Mīr Ma˓ṣūm in the16th century attests to the Arghūn and then Tarkhān dynasty that hold on the fort of Sīwistān until the Mughal conquest, but the excavations have not yielded any coins from these periods. Mīr Ma˓ṣūm also indicates that the site was a military fortress at this time. Metallurgical activity is shown by the presence of iron slag and crucibles, but more broadly the excavations have shown despite a repair of the fort, a loose occupation of the site,. The quality of the ceramic material red declines and the glazed wares are coarse, heavy and only monochrome. Only the ceramics with moulded decoration are fine and of quality (fig. 9).

A palatial residence was partially excavated, overlooking the north-western area of the site where a bath was uncovered, with ceramic material mainly from the surface and from the excavations of the structures.They were associated with ceramic tiles that had fallen from the walls they covered, and with shards of Chinese porcelains and celadons. Other excavated areas, as in the center of the fort, have uncovered much more common ceramic material (fig. 10).
