Riad: A riad is a traditional Moroccan house or palace with an interior garden or courtyard. The word riad comes from the Arabian term for garden, "ryad".
The riads were inward focused, which allowed for family privacy and protection from the weather in Morocco. This inward focus was expressed in the central location of most of the interior gardens and courtyards and the lack of large windows on the exterior clay or mud brick walls. In the central garden of traditional riads there are often four orange or lemon trees and possibly a fountain. The walls of the riads are adorned with tadelakt plaster and zellige tiles, usually with Arabic calligraphy, with quotes from the Quran.
