Hisn Yakka is the name given to an old Muslim fortress and town, predecessors of the current city of Yecla. It was inhabited between the 11th and 13th centuries, as the town was abandoned after 1266 after the Mudejar revolt and the new Christian settlers settled on the opposite side of the mountain.
Hisn Yakka was built at the end of the 11th century in the Almoravid period, but it was not until the 12th century that the town or Madina appeared on the sunny side.
After the Christian conquest of the kingdom of Murcia, the Muslim population became a vassal of the King of Castile, which made the living conditions of the population more difficult, discontent that caused the Mudejar revolt. A large part of the Mudejar population had to leave the area at the end of this revolt, and it is likely that this was also the end of Yakka.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
