The MMC was an industrial facility that produced food, uniforms and other goods for the Portuguese Army. During the twentieth century the complex was expanded. Whilst the Portuguese Army reached 200.000 men in the 1960’s, it is now reduced to 20.000 active soldiers. Gradually the factories closed and Manutencao Militar was finally substituted by a public enterprise in 2015. The termination of the industrial production raised the problem of finding new sustainable uses for this area on the Tagus riverfront, between the Pombaline City Harbour and the Contemporary Parque das Nacoes. This is a challenging task: any future solution needs to have a dialogue with this current industrial heritage, which is deeply connected with recent Portuguese history, as well as with the Lisbon riverside area and the contemporary city.
