From the Alcazaba, descend in a northward direction through the Barranco de la Hoya, a line of wall that reaches San Cristobal Hill was built during the time of King Jairán (1012-1028) in the eleventh century. Here are the remnants of the neighbourhood amurallamiento musalla, which descends from the hill via the main street Antonio Vico.
On the hill, known in Muslim times as Monte Laham, there are seven towers, three square Muslim towers and four semicircular Christian towers. These were built by the Templars of Alfonso VII, who constructed a strong-chapel following the Christian conquest of the city under the command of the troops of Alfonso VII in 1147.
On this hill, which has an impressive view of the city, and located on a large pedestal, is the image of the Sacred Heart of Jesus, constructed of local Macael marble. It was restored in 2000 and it is said to bless the city and the Mediterranean Sea. It was originally built in the twentieth century (around 1930).
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
