In the town of Lalibella the walls of many houses are made of stone and are two-storied, while in parts of Tigre, houses are traditionally rectangular.
In more urban areas, a mixture of tradition and modernity is reflected in the architecture. The thatched roofs often are replaced with tin or steel roofing. The wealthier suburbs of Addis Ababa have multistory residences made of concrete and tile that are very western in form. Addis Ababa, which became the capital in 1887, has a variety of architectural styles. The city was not planned, resulting in a mixture of housing styles. Communities of wattle-and-daub tin-roofed houses often lie next to neighborhoods of one- and two-story gated concrete buildings.
Many churches and monasteries in the northern region are carved out of solid rock, including the twelve rock-hewn monolithic churches of Lalibela. The town is named after the thirteenth-century king who supervised its construction. The construction of the churches is shrouded in mystery, and several are over thirty-five feet high. The most famous, Beta Giorgis, is carved in the shape of a cross. Each church is unique in shape and size. The churches are not solely remnants of the past but are an active eight-hundred-year-old Christian sanctuary.
