period. The use of exposed chamfered brickwork and the use of exposed structural ironwork gives the building an industrial look, solid and compact on the lower levels but agile and transparent above, with its pierced parapets crowned by a pinnacle. The interior is an open space with two arches that support a stepped, symmetrical roof. Domènech incorporated the best of the applied arts and ornamental solutions that became permanent, such as the florid crowns of the capitals. Ceramics from the Pujol i Bausis factory were used, with designs by Antoni M. Gallissà, Josep Llimona, J.A. Pellicer and Alexandre de Riquer. There were also stained glass windows by Antoni Rigalt i Blanch, but these have now perished.

In all of these he adopted an integral approach to modernisme, with an intensive use of the applied arts, particularly sculpture, mosaic and stained glass. The major works At the height of his professional career, Domènech i Montaner took on his largest and most complex works, the ones for which he is most widely recognized. His work on these projects overlapped in time, and he was able to take advantage of the experience gained on each one. Much of the knowledge gained and many of the technical innovations employed on the Expo restaurant (the Castell dels Tres Dragons, now the geology museum) were later used in the design and construction of the Palau de la Música, and the avant-garde concepts applied in the Institut Pere Mata were later adopted and improved on at the Hospital de Sant Pau. The Palau de la Música Catalana and the Hospital de Sant Pau both won awards in the annual architectural competition organized by the Barcelona City Council, in 1905 and 1913 respectively. More recently UNESCO has declared them to be World Heritage. Institut Pere Mata Before the 19th century came to an end, at the height of modernisme, Domènech built the Institut Pere Mata, an institution for the mentally ill in Reus (1897–1919). It is an example of architecture at the service of people, without neglecting the purely aesthetic aspect. It was begun with the support
