The name "Palácio de Cristal" comes from the old palace that once stood on the site, which was demolished in 1951. Today, the gardens are a place of great cultural and tourist importance for the city of Porto. The Jardins do Palácio de Cristal are a complex of public gardens located in the city centre of Porto, Portugal. It was created in 1860 and is considered one of the most important urban gardens in Europe.

The Crystal Palace, designed by the English architect Thomas Dillen Jones, was built in granite, iron and glass, using the Crystal Palace in London as its model. It measured 150 metres long by 72 metres wide and was divided into three naves. Its construction began in 1861, and it was inaugurated on 18 September 1865 by King Luís. It was designed to host the great Porto International Exhibition, organised by the then Associação Industrial Portuense, now the Associação Empresarial de Portugal. The Industrial Exhibition, in addition to the official visit of King D. Luís, Dona Maria Pia and the Crown Prince, also had 3,139 exhibitors, of which 499 were French, 265 German, 107 British, 89 Belgian, 62 Brazilian, 24 Spanish, 16 Danish and also representatives from Russia, the Netherlands, Turkey, the United States and Japan. Over its 86 years of existence, the Palácio de Cristal hosted many other exhibitions, including the rose exhibition in 1879, the agricultural exhibition in 1903 and the Portuguese Colonial Exhibition, which opened in June 1934. From this last exhibition, the Monument to the Portuguese Colonization Effort survives, currently located at the western end. from Avenida do Marechal Gomes da Costa. The Crystal Palace was also an important cultural space, containing a pipe organ that was one of the largest in the world. It was in this palace that important concerts by the composer Viana da Mota and the virtuoso cellist Guilhermina Suggia were held. The palace was destroyed in 1951, and in its place a reinforced concrete nave was built, which was given the name of Sports Pavilion, according to a project by architect José Carlos Loureiro and engineer António dos Santos Soares and on the pretext of the Roller Hockey World Championship. The building was demolished in less than a year, with the pipe organ being destroyed with a hammer. Due to popular protests against the demolition, the name Crystal Palace has survived to this day.
