This borj, also called Kasbah,
is a fortress built at the end of the XVIth century
on the site of the former Fatimid palace and is
considered one of the finest specimens of Ottoman
Built on a quadrangular plan and later endowed
with corner bastions, the building is surrounded
by strong walls originally with one entrance only
(after it was turned into a prison, another access
was added in the XIXth century). This door leads
through a vaulted and elbowed passage, into a
courtyard onto which various vaulted rooms open.
In the south-eastern corner of the courtyard,
an earlier oratory was conserved and integrated
into the building.
From the wall-walk, converted to a terrace, there
is a lovely view over the tip of the Cape Mahdia
promontory and, closer to the monument, over the
ancient harbour basin that certain specialists
date to the Punic period.
