features several rectangular garden courtyards with decorated pavilions at either end and it was originally linked to the Alhambra by a walled corridor that crosses the valley between the two. It underwent modifications and redecoration under multiple later Nasrid rulers. The Generalife also underwent major alterations by Christian Spanish builders in the 16th century, which imparted Renaissance elements on the palace. In the 20th century a large area of modern landscaped gardens, known as the Jardines Nuevos ('New Gardens'), were added to the south of the Nasrid palace and form the main approach to it today. These date in large part to the work of Leopoldo Torres Balbás and Francisco Prieto Moreno, between 1931 and 1951, who incorporated both Italian and Moorish influences in their design. An open-air auditorium was also added in 1952. Along with the Alhambra, the Generalife is a major tourist attraction and was declared a UNESCO World Heritage Site in 1984. Cathedral The cathedral of Granada is built over the Nasrid Great Mosque of Granada, in the centre of the city. Its construction began during the Spanish Renaissance in the early 16th century, shortly after the conquest of Granada by the Catholic Monarchs, who commissioned the works to Juan Gil de Hontañón and Enrique Egas. Numerous grand buildings were built in the reign of Charles V, Holy Roman Emperor, so that the cathedral is contemporary to the Christian palace of the Alhambra, the University and the Real Chancillería (Supreme Court). The church was conceived on the model of the Cathedral of Toledo, for what initially was a Gothic architectural project, as was customary in Spain in the early decades of the 16th century. However, Egas was relieved by the Catholic hierarchy in 1529, and the continuation of the work was assigned to Diego Siloe, who built upon the example of his predecessor, but changed the approach towards a fully Renaissance aesthetic. The architect drew new Renaissance lines for the whole building over the gothic foundations, with an ambulatory and five naves instead of the usual three. Over time, the bishopric continued to commission new architectural projects of importance, such as the redesign of the main façade, undertaken in 1664 by Alonso Cano (1601–1667) to introduce Baroque elements. In 1706 Francisco de Hurtado Izquierdo and later his collaborator José Bada built the current tabernacle of the cathedral. Highlights of the church's components include the main chapel, where
