CCFL 501, introduced in 1995, briefly stops at Praça do Comércio. It will proceed to Algés, closely following the pioneer tram route opened on August 31, 1901, from Cais do Sodré to Ribamar. Today, route 15, from Praça da Figueira to Algés, provides a comfortable access to many relevant monuments and museums. 2008 Paulo Santos / Arquivo de Transportes (http://atransportes.multiply.com)
