Ciudad Real is a city in Castile-La Mancha, Spain. It is the capital of the province of Ciudad Real. It has a stop on the AVE high-speed rail line and has begun to grow as a long-distance commuter suburb of Madrid, located 115 miles (185km) to the north. A high capacity airport (Ciudad Real Central Airport) has been built to serve the city. It is now open, but has little traffic. The beginning of the construction of a new Caesar's Palace Casino is planned. During the Middle Ages, four kilometres of walls and one hundred and thirty towers protected a population made up of Christians, Muslims and Jews. The city was surrounded by walls. Nowadays, there are only two parts of the wall left.
