Located on the southern edge of the Amman Citadel, the so-called Ayyubid Tower is the only surviving medieval fortification visible on the citadel today. Although the Frankish presence in Amman during the 12th century is attested historically, especially under Philip of Milly and later the Templars, their associated fortifications have not been securely identified. The tower has been interpreted instead as Ayyubid based on a coin recovered from its construction fill, which provides a terminus post quem of 1190–1191 CE (Sinibaldi 2014:62; Northedge et al. 1992:113–114, JW: This last sentence could be a hallucination).

Built of large, roughly dressed stones, the tower is rectangular in plan and is part of a wider phase of military reoccupation and construction on the Amman Citadel during the Ayyubid period, following the decline of Crusader control in Transjordan. Archaeological evidence suggests that the tower may have been part of a short-lived fortification effort, possibly linked to Saladin's campaigns or local governors seeking to secure the citadel. While modest in scale, its survival has made it an important feature for dating later phases of medieval activity on the site.

Chronology
Level III Earthquake - 11th - 13th centuries CE

Discussion

Sinibaldi (2014:62) reports that rescue excavations by Crystal-M. Bennett at the Amman Citadel between 1975 and 1979 uncovered significant collapse deposits (level III) in Areas B, C, and D. These strata are interpreted as representing the final phase of occupation prior to site-wide abandonment. The associated pottery assemblages were similar across all three areas, suggesting a single destructive event—most likely an earthquake— was responsible. A terminus post quem of 1021 CE was provided by a coin in the stratigraphy. Sinibaldi (2014:62) notes that the destruction may have occurred later, possibly as a result of earthquakes recorded between the 12th and 13th centuries/

According to Sinibaldi (2014:240–241), pottery typologies in level III support a later date. Cooking pots from the collapse layer correspond to 12th-century Beirut-type wares—globular, thin-walled vessels with pulled-up handles and indented bands. One well-preserved example, found as if it had fallen from a cupboard or niche, reinforces the interpretation of a sudden seismic event. The absence of handmade pottery in level III, contrasted with its appearance in later Ayyubid levels (dated by coins to the late 12th–early 13th century), further suggests a temporal break marked by destruction. However, due to the poor definition of 11th-century ceramic sequences in Jordan, a precise date cannot be securely fixed (Sinibaldi, 2014:240–241). Nonetheless, the evidence, according to Sinibaldi (2014), supports the hypothesis that the citadel was heavily damaged by an earthquake sometime between the mid-12th and early 13th centuries.

Notes by JW

Sinibaldi (2014:62) reports the following:

One of the Frankish castles held by Philip of Milly in 1161 and by the Templars in 1166 was in Amman,321 (and not in Ma‘an), but it is still not safely identified with material remains. A likely site would be the Citadel. However, the only surviving medieval fortified structure in the citadel, tower B, has been interpreted as Ayyubid on the basis of a coin dated 1190-91, used as a terminus post quem.322 Rescue excavations by Crystal-M. Bennett between 1975 and 1979 exposed the last phases of occupation at the site, whose abandonment has been interpreted as caused by an earthquake. Areas B, C and D, which were abandoned after the collapse, yielded similar pottery in the collapse level (level III)323 to suggest that all these areas were affected by the same event which caused the abandonment; the inhabitants did apparently not have the resources to reconstruct the area. The possible earthquake post-dated 1021 A.D., a date offered by a coin in the stratigraphy; Northedge proposes that the most likely earthquake affecting this situation was the one that occurred in AD 1068.324

However, it cannot be excluded that the earthquake occurred later,325 and in fact this possibility may be supported by the pottery found in level III.326 Possible earthquakes in the 12th /13th centuries affecting Amman include those of 1139, 1170,1202, 1212, 1293, 1312, one of the most intense at that time being the one of 20 May 1202, which affected for example the castle of Jacob’s Ford (Vadum Iacob, le Chastelez) in the Jordan Valley; any of these, however, could have equally affected the citadel.327

Amman

Several examples of cooking pots from level III (the collapse that caused the abandonment of the site) at the Amman citadel have similarities with the 12th-13th century type well recorded in Israel as being produced in Beirut, although affinities are in particular with the earlier 12th-century type.1126 Similarities to these earlier variations occur in several examples,1127 although some of these cooking pots examples are certainly earlier than the Crusader period.1128 It has been observed not only that the early (12th century) type is globular, thin-walled and with an out-turned or straight rim (as opposed to the later type, thick-walled and deep in form), but also that an evolution observable in the 12th century is that at this moment the handles become more pulled up and narrower.1129

A cooking pot from group 8, building 1 in particular clearly belongs to this type, whose dating covers the second half of the 12th century and the first half of the 13th century.1130 The hypothesis of an earthquake was supported in particular by the recovery of this object, which judging from its position and almost perfect preservation, apparently fell from a cupboard or niche.1131 The cooking pot has an applied indented band, which is a very common element of this type,1132 a straight rim and glaze on the interior. The same phase includes types which have a very long duration and were in use in the 12th century, such as the large bowls with thumb-indented bands and comb decorations that are attested for the 12th century and later.1133

Unfortunately, the chronological separation between the late Fatimid and the early Crusader periods for this type is difficult, as the variations throughout these periods seem to be very minor.1134 A problem in isolating pottery of the 12th century is the fact that 11th-century pottery is not well known especially in Jordan, both for this specific type and in general. However, the possible evidence of 12th-century pottery in this specific context allows for an hypothesis that if the citadel was seriously damaged by an earthquake, it was during the 12th century or later, although probably not much earlier than around mid-century.

It is interesting that handmade pottery is almost absent in the assemblage of level III, and seems to appear only in the Ayyubid phases, dated by coins to the late 12th century-early 13th century.1135 There appears to be a gap between the abandonment and the reoccupation of the site, during the 11th/12th century; the gap cannot however be so long to justify this sudden introduction of handmade pottery. As it is well known, handmade pottery is already present in the 12th century in Transjordan. It is possible, therefore, that the presence of handmade pottery reflects rather the different function of settlement rather than chronology, i.e. it could have been more open to the import of ceramic products during the Crusader period, while after it, the site may have only attracted local pottery. However, it can also be noticed that no stratified glazed imports of the 12th century have been found.

  • VIII+?
  • VII+
The archeoseismic evidence requires a minimum Intensity of VII (7) or possibly VIII (8) when using the Earthquake Archeological Effects chart of Rodríguez-Pascua et al (2013: 221-224). The Amman Citadel may be subject to a ridge effect.
