Any survey of tiles as public art, no matter how brief, should mention the vast number of huge, beautiful schemes in Portugal, many of which have been designed by women. An incredible amount of exterior surface area in Lisbon is covered with the work of Maria Keil (1914-2012); her designs appear in ten of the first metro stations in Lisbon (work undertaken 1955-1972) including Anjos station (1966, above). She made her name as the first Portuguese artist to give azulejos (tiles) a modern look, and played a major role in the development of the contemporary Portugese cultural life. This Azulejo route in Lisbon sounds marvellous.
