Events

Arquivo.pt joined the celebrations of the 50th anniversary of April 25, the Portuguese Revolution of 1974, as part of the initiatives promoted by the Fundação para a Ciência e a Tecnologia (FCT) in partnership with the Estrutura de Missão – Comissão Comemorativa 50 anos 25 de Abril.

The initiatives were as follows: a journey through time, a special collection on the theme “Abril 25”, a presentation at the “50 years of April International Congress” and the inclusion of a special mention in the 2025 edition of the Arquivo.pt Award.

Memories of April 25 on the Internet exhibition

The exhibition Memories of April 25 on the Internet presents a selection of web pages about the celebrations of April 25 in various regions of the country, since the beginning of the web in the 1990s.

The criteria for choosing the pages for the exhibition were as follows:

• Pages relating to the April 25 commemorations;
• Pages found on Arquivo.pt on dates close to the anniversary each year;
• Diversity to include different areas of the country;
• Popular demonstrations and official ceremonies.

A historical memory without web archives is incomplete. The aim of this journey through time is to invite citizens to travel back in time, browsing through old web pages and reliving recent episodes in our life as a democracy.

Special collection on April 25 – the Portuguese Revolution of 1974

To mark the anniversary, Arquivo.pt carried out a special collection on the topic of “April 25” and made the results available in an open dataset, published on the Dados.gov portal.

The dataset contains a list of keywords put into a search engine in order to obtain results on the topic of “April 25”. The search considered names of people, places, political, social and cultural aspects, as well as words associated with the event.

The searches were carried out on March 22, 2024 using the Bing Search API, an automatic search service that returns results according to the relevance criteria of the Bing service itself and others configured by us.

A total of 12,650 unique web page addresses were obtained. It is hoped that the recording of these pages will be useful for the organizations that produced this content, for researchers who want to study our history and for citizens who cultivate a sense of memory and democracy.

Participation in the 50 years of April International Congress

On May 2, 2024, João Gomes, Director of Advanced Services at the FCCN Scientific Computing Unit of the Foundation for Science and Technology I.P., presented Arquivo.pt to the participants of the 50 years of April International Congress, as a distinctive service, open to citizens and useful for organizations.

This event, organized by the Estrutura de Missão – Comissão Comemorativa 50 anos 25 de Abril and the University of Lisbon, included a presentation of two FCT services for citizens: Arquivo.pt and NAU’s massive online open courses.

Arquivo.pt is a web preservation service available to all citizens who want to search for old content published on the web.

Using Arquivo.pt contributes to a better understanding of our history. It also provides useful services for cybersecurity, such as the Arquivo.pt Memorial, which is able to maintain institutions’ old websites, preventing attacks and saving them resources.
