Borj el-Kebir, sometimes called Borj Ghazi Mustapha, has had many owners over the years. It was the Romans building the first recorded stronghold here, but it was the king of Sicily, Roger de Lluria, who in 1289 built the very first fortress. In 1560, the Spanish (who had it transferred from Sicily earlier in history) were driven out by the Ottoman forces. Hundreds, if not thousands, of skulls from the Spanish soldiers were kept on display inside a tower for almost 200 years. Most of the fort was rebuilt by the Ottomans, and hence little would date back as far as to the time of the Sicilians.
