Nonetheless, while this policy preserved historic monuments, it also had other consequences in the long-term by stalling urban development in these heritage areas and causing housing shortages in some areas.[30] It also suppressed local Moroccan architectural innovations, as for example in the medina of Fez where Moroccan residents where required to keep their houses – including any newly built houses – in conformity with what the French administration deemed to be the historic indigenous architecture.[31] In some cases French officials removed or remodelled more recent pre-colonial Moroccan structures which had been visibly influenced by European styles in order to erase what they deemed as foreign or non-indigenous interference in Moroccan architecture, such as the Bab Campini gate (now known as Bab Chems), which was built in an Italianate style in the 19th century but was rebuilt by the French in a "Moorish" style.[31]
