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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
