I want to know the answer to the following question:
What were walled quarters known as?
All the background I'm provided with is that "Notable exceptions include the massacre of Jews and forcible conversion of some Jews by the rulers of the Almohad dynasty in Al-Andalus in the 12th century, as well as in Islamic Persia, and the forced confinement of Moroccan Jews to walled quarters known as mellahs beginning from the 15th century and especially in the early 19th century.". Is that enough to answer the question?
Answer: yes
