The Communications Museum is the most visible face of the Portuguese Communications Foundation, created on October 6th, 1997, by its founding members ANACOM – National Communications Authority, CTT – Portuguese Postal Services and PT - Portugal Telecom (now Altice).

The Museum is an active element in the execution of the Foundation's primary mission: to promote the study, conservation and dissemination of the historical, scientific and technological communications heritage.

At the Communications Museum - a living science and technology workshop - children and grown-ups alike can discover how much fun communicating can be. Focusing on the general public and students, the Education Department runs pedagogical programmes, themed visits and entertainment based on the exhibitions that morph into real guided journeys through the history of communications in a fun and interactive format.

Besides the permanent exhibitions, the Museum also organises temporary exhibits and welcomes public interest initiatives that deserve to be seen in such an open and dynamic space.
