when was the cathedral of santiago de compostela built
Santiago de Compostela Cathedral Construction of the present cathedral began in 1075 under the reign of Alfonso VI of Castile (1040–1109) and the patronage of bishop Diego Peláez. It was built according to the same plan as the monastic brick church of Saint Sernin in Toulouse, probably the greatest Romanesque edifice in France. It was built mostly in granite. Construction was halted several times and, according to the Liber Sancti Iacobi, the last stone was laid in 1122. But by then, the construction of the cathedral was certainly not finished. The cathedral was consecrated in 1211 in the presence of king Alfonso IX of Leon.[9][10]
Volcanology of Chile Volcanology of Chile studies a continuous volcanic process that has a strong influence on Chilean landscape, geology, economy and society. Volcanism constantly renews the Chilean landscape with lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes, calderas, diatremes, and maars. However volcanism in Chile as well as in other parts of the world is also associated with several natural hazards such as lahars, earthquakes, pyroclastic flows, toxic gases and ash. Continental Chile has a high concentration of active volcanoes due to its location along the Peru–Chile Trench, a subduction zone where the Nazca and Antarctic Plates are driven beneath the South American Plate. Chile has been subject to volcanism since at least late Paleozoic when subduction along the western margin of South America began. Easter Island, Juan Fernández Islands and other oceanic islands of Chile are extinct volcanoes created by hotspots. Chile has about 500 volcanoes considered active, 60 of which have had recorded eruptions in the last 450 years. The volcanoes with most recorded eruptions are:
