The final and most significant change to Fes's topography was made during the reign of Moulay Hasan I (1873-1894), who finally connected Fes el-Jdid and Fes el-Bali by building a walled corridor between them.[3][2] Within this new corridor, between the two cities, were built new gardens and summer palaces used by the royals and the capital's high society, such as the Jnan Sbil Gardens and the Dar Batha palace.[3][27] Moulay Hassan also expanded the old Royal Palace itself, extending its entrance up to the current location of the Old Mechouar while adding the New Mechouar, along with the Dar al-Makina, to the north. This had the consequence of also splitting the Moulay Abdallah neighbourhood to the northwest from the rest of Fes el-Jdid.[27]
