The Bock is a promontory in the north-eastern corner of Luxembourg City's old historical district. Offering a natural fortification, its rocky cliffs tower above the River Alzette which surrounds it on three sides. It was here that Count Siegfried built his Castle of Lucilinburhuc in 963, providing a basis for the development of the town which became Luxembourg. However, the Romans and later Franks had probably already inhabited the Bock although there is only scant archeological evidence of their presence. There are however traces of a 4th-century Roman watchtower close to the point in the Fish Market where two major Roman roads used to cross, one from Reims to Trier and the other from Metz to Liège.
Over the centuries, Siegfried's fortified castle on the Bock was considerably enlarged and protected with additional walls and defences. In 987, the castle chapel was built at the nearby Fish Market. Today's St Michael's Church stands on the same site. Under Conrad I, the castle became the residence of the Counts of Luxembourg. It was damaged, destroyed, captured and rebuilt on several occasions as the Burgundians (1473), the Habsburgs (1477), and the Spaniards (1555) attacked and took the fortress.
As time passed, the fortifications needed to be adapted to new methods of war based on increasingly strong firepower. During the 1640s under the Spaniards, the Swiss engineer Isaac von Treybach significantly reworked the defences. The Bock was also strengthened with three forts, the Large Bock, Middle Bock and Small Bock (from west to east), separated from each other by cuts in the rock and linked by bridges. As a result, little remained of the medieval castle.
A little later in 1684, on behalf of Louis XIV, Vauban succeeded in capturing the city of Luxembourg during a month-long siege under which the Bock fortifications were completely flattened. Thereafter Vauban, perhaps the most competent fortification engineer of his day, undertook major additions to the defences, realizing that underground passages and chambers were just as important as the surface installations. The Large Bock, connected to the old town by the Pont du Château, was further reinforced. Enclosed by a wall 12 m high, it was the major component of the new fortress.
In addition to these structures, the Bock also included a system of casemates which originated in the cellars of the medieval castle. In 1744, during the Austrian period, these underground passages were considerably enlarged by General Neipperg. The main passage. which still remains, is 110 m long and up to 7 m wide. Branches leading off on either side were equipped with no less than 25 cannon slots, 12 to the north and 13 to the south, offering considerable firepower. In the event of war, the Bock casemates, covering an area of 1,100 m2, could be used as barracks for several hundred soldiers.
Thanks to its defences, in 1794 during the French Revolutionary Wars, the city held out against the French siege for seven months. When the garrison finally surrendered, the walls were still unbreached. The fortifications were finally demolished under the terms of the Treaty of London in 1867. The demolition took 16 years and cost the enormous sum of 1.5 million gold francs.
In 1933, the Bock casemates were opened to the public. During the Second World War, they were used as a bomb shelter able to accommodate up to 35,000 people. In 1994, the casemates were added to the list of UNESCO's world heritage sites, attracting some 100,000 visitors a year. Renovation work and repairs were undertaken in 2008–2009 including the opening up of the mine galleries which contained explosives able to blow up part of the Bock in case of need.References:
Castle of Lorca (Castillo de Lorca) is a fortress of medieval origin constructed between the 9th and 15th centuries. It consists of a series of defensive structures that, during the Middle Ages, made the town and the fortress an impregnable point in the southeast part of the Iberian Peninsula. Lorca Castle was a key strategic point of contention between Christians and Muslims during the Reconquista.
Archaeological excavations have revealed that the site of the castle has been inhabited since Neolithic times.
It has not been determined exactly when a castle or fortress was first built on the hill. The first written documentation referring to a castle at Lorca is of Muslim origin, which in the 9th century, indicates that the city of Lurqa was an important town in the area ruled by Theudimer (Tudmir). During Muslim rule, Lorca Castle was an impregnable fortress and its interior was divided into two sections by the Espaldón Wall. In the western part, there was an area used to protect livestock and grain in times of danger. The eastern part had a neighbourhood called the barrio de Alcalá.
Lorca was conquered by the Castilian Infante Don Alfonso, the future Alfonso X, in 1244, and the fortress became a key defensive point against the Kingdom of Granada. For 250 years, Lorca Castle was a watchpoint on the border between the Christian kingdom of Murcia and the Muslim state of Granada.
Alfonso X ordered the construction of the towers known as the Alfonsina and Espolón Towers, and strengthened and fixed the walls. Hardly a trace of the Muslim fortress remained due to this reconstruction. Muslim traces remain in the foundation stones and the wall known as the muro del Espaldón.
The Jewish Quarter was found within the alcazaba, the Moorish fortification, separated from the rest of the city by its walls. The physical separation had the purpose of protecting the Jewish people in the town from harm, but also had the result of keeping Christians and Jews separate, with the Christians inhabiting the lower part of town.
The remains of the Jewish Quarter extended over an area of 5,700 square m, and 12 homes and a synagogue have been found; the synagogue dates from the 14th century and is the only one found in the Murcia. The streets of the town had an irregular layout, adapted to the landscape, and is divided into four terraces. The synagogue was in the central location, and around it were the homes. The homes were of rectangular shape, with various compartmentalized rooms. The living quarters were elevated and a common feature was benches attached to the walls, kitchens, stand for earthenware jars, or cupboards.
With the disappearance of the frontier after the conquest of Granada in 1492, Lorca Castle no longer became as important as before. With the expulsion of the Jews by order of Ferdinand and Isabella, Lorca Castle was also depopulated as a result. The castle was abandoned completely, and was almost a complete ruin by the 18th century. In the 19th century, the castle was refurbished due to the War of Spanish Independence. The walls and structures were repaired or modified and its medieval look changed. A battery of cannons was installed, for example, during this time. In 1931 Lorca Castle was declared a National Historic Monument.
Currently, a parador (luxury hotel) has been built within the castle. As a result, archaeological discoveries have been found, including the Jewish Quarter.
