The Kasbah of the Udayas, also known as Kasbah des Oudaias, is a historic site located in Morocco's capital, Rabat. This ancient fortress, perched on a cliff overlooking the Bou Regreg River and the Atlantic Ocean, was built during the reign of the Almohads in the 12th century. The Kasbah is famed for its narrow, winding alleyways lined with white and blue houses, reminiscent of a Mediterranean style. It houses the Andalusian Gardens, filled with blooming flowers and citrus trees, and the Kasbah Mosque, one of the oldest mosques in Rabat. The site also features a museum showcasing Moroccan arts and crafts. The Kasbah of the Udayas is a UNESCO World Heritage Site and a must-visit for its stunning views and rich history.
