Avila is one of the historical jewels of the crown of Spain. Cities around the world are witnesses of many past events and Avila is no exception. It has seen the Moorish as well as the Christian rule, and both of these eras have left their footprints on the city in form of monasteries, Romanesque churches, convents, and forts. The city is walled and therefore, all of these landmarks are guarded well, and because of their antique nature, the whole city is listed by UNESCO.
In Spain, nearly every city has an Alcazar – a fortification of Moorish origin or of the Christian origin.
The Avila can very much be called a fort in itself. This is because this city is bound by walls that were built for fending off any invasions. There are nine gates in the Alcazar de Avila with the Gate of St. Vincent and Gate of the Fortress (Puerta del Alcazar) flanked by two towers of 20-meter height.
