Pigeon houses at Mit Gahmr, Egypt
Pigeon is a part of the daily diet in many parts of Egypt and Pigeon houses, or dovecotes, are constructed from mud brick create an artificial mountainous topography. The droppings are also a valuable source of fertilizer and the houses are so ubiquitous that they are also part of the Egyptian national identity. The dovecote typology can be found throughout the world and Earth Architecture has previously featured the palomares of Spain.
Interestingly, the Egyptian pigeon houses remind one of the recent work of architect Vicente Guallart, who in his project The Re-Naturalization of Territory, attempts to create what could be considered as dovecotes for biotechnology and cinema in Tarragona, Spain.
