Object description

The Graciosa fortress was established on the coast of Morocco by the Portuguese in 1489. It was established on a small river island, about three leagues from the sea, at the junction of river Lucus and river el-Mekhazen , a few kilometers inland from modern Larache. The island had been yielded to the Portuguese by Abu Zakariya Muhammad al-Saih al-Mahdi through a treaty following the Portuguese capture of Arzila.
