Valencia has since then experienced a surge in its cultural development, exemplified by exhibitions and performances at such iconic institutions as the "Palau de la Música", the "Palacio de Congresos", the Metro, the City of Arts and Sciences "(Ciutat de les Arts i les Ciències)", the Valencian Museum of Enlightenment and Modernity "(Museo Valenciano de la Ilustracion y la Modernidad)", and the Institute of Modern Art "(Institut Valencià d'Art Modern)". The various productions of Santiago Calatrava, a renowned structural engineer, architect, and sculptor and of the architect Félix Candela have contributed to Valencia's international reputation. These public works and the ongoing rehabilitation of the Old City "(Ciutat Vella)" have helped improve the city's livability and tourism is continually increasing.
