Tram 28 is one of only three traditional tram lines that still operate in Lisbon. These trams, which until the late-1980's ran all through-out Lisbon, were manufactured between 1936 and 1947. Tram 28 winds its way through the "Old Town" of Lisbon (dating from the 17th century) beginning in Graça then down to the Alfama and to the Baixa then up through Chiado to Bairro Alto and then down to Campo Ourique, taking you by many of Lisbon's most famous and interesting sites including monuments, churches and gardens. The trip is hilly, noisy and hectic but it affords many beautiful glimpses of the city.
