Bordj el Baroud

The ruins located south of the mouth of Oued Ksob is known as "Bordj el Baroud " or "Borj el Baroud".
Late 18th century construction of defensive fortresses included Borj el Bermil at the entry of the port, Borj el Assa at the island of Mogador ( Ile Purpuraires ) and Borj el Baroud south at the Oued Ksob.
Borj el Baroud was an isolated fortress which served as a store for gunpowder probably situated somewhere between Bab Marrakech and Sidi Mogdoul. There are no traces left of it today caused by the new settlements and the construction of Boulevard Mohammed V.

The Phoenician explanation:

"I suggest this structure may have been an integral part of the Ile Purpuraires Phoenician settlement for the following reasons:
(i) The position of Bordj El Berod is directly opposite the Phoenician fort at the southeast tip of Ile Purpuraires, permitting a pincer effect upon naval monitoring into the harbour via the southern approach; (Google, 2007)
(ii) The bordj El Berod follows the classic form of Phoenician coastal construction using an immense natural rock as the foundation;
(iii) The stonework follows Phoenician practises of mixing different stone types within the same structure. In particular most of the stonework utilises a native red stone hewn into large rectilinear blocks, but a prominent horizontal course is evident which uses a lighter gray colour hewn in smaller blocks and faced in a cylindrical fashion.
(iv) The condition of the ruined Bordj is remarkable, given its exposure to surf and salty mist. The condition of mortar exposed to these elements is more suggestive of Phoenician engineering, whose talents regularly attacked severe coastal conditions, whereas later Moorish mortar was not as durable to these extreme marine conditions and indeed was not called upon for many such assignments.
(v) The location of Bordj El Berod is remarkably consistent with a fort suitable for monitoring the trading practises that Heroditus depicts in describing the Phoenicians laying out their wares on a broad beach for local tribes to purchase;
(vi) The destruction of the Bordj El Berod was most likely associated with the 18th century major earthquake in western Morocco, making it unlikely that any significant part of the Bordj was associated with the mainstream Moorish construction of Essaouira that occurred in the late 18th century and beyond; and
(vii) The existence of such a grand mainland watchtower would clearly justify naming the site after the Phoenician word ‘'migdol'‘ or watchtower..
