The magnificent Castillo de Gibralfaro sits on a high hill overlooking Málaga city and, and dates back to the 10th century. Gibralfaro has been the site of fortifications since the Phoenician foundation of Málaga city, circa 770 BC. The location was fortified by Calif Abd-al-Rahman III in 929 AD. While, At the beginning of the 14th century, Yusuf I of the Kingdom of Granada expanded the fortifications within the Phoenician lighthouse enclosure and erected a double wall to Alcazaba. The name is said to be derived from Arabic, Jbel, rock or mount, and Greek the word for light, Jbel-Faro, meaning 'Rock of Light'. The castle is famous for its three-month siege in 1487 by the Catholic monarchs, King Ferdinand and Queen Isabella, which ended when hunger forced the Malagueños to surrender.
The most visible remains of this historic monument are the solid ramparts which rise majestically from dense woods of pine and eucalyptus; inside the fortress itself you will find some buildings and courtyards, reminiscent of those in the Alhambra. The ramparts have been well restored and you can walk all the way round them. At one point, you can get a good view down into the La Malagueta bullring - some visitors linger for a free view of the bullfight. These walls make a fun, interesting and scenic walk, and usually you will have it to yourself, as there aren't many tourists about.References:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
