Traditional architecture in the United Arab Emirates was heavily influenced by the desert landscape, culture, lifestyle and available building materials.[5] The Bedouin, a nomadic Arabic tribe who traditionally live in the desert were well known for using palm frond shelters, known as Arish in the summer months.[citation needed] Frames for Arish houses were often made with mangrove poles, imported from East Africa. In colder months, a move towards using animal skin shelters would be made.
