It was extensively renovated around 1300 by King Denis I, transforming the Moorish alcáçova into the Royal Palace of the Alcáçova. Between 1373 and 1375, King Ferdinand I ordered the building of the ''Cerca Nova'' or ''Cerca Fernandina'', the walled compound that enclosed all but the north flank of the castle. The master builders João Fernandes and Vasco Brás were responsible for its construction.

On 6 November 1648, Nicolau de Langres was called upon to take over the design, execution and construction of a new fortification that would surround the Castle of Saint George and the city walls of Lisbon. In 1650 the military architect Mateus do Couto was named master builder of the project and reconstruction took on a new formality: although the military engineer João Gillot built new walls in 1652, construction again followed Couto's plans between 1657 and 1733. In 1673, the Soldiers' Hospital, dedicated to ''São João de Deus'' (St John of God), was installed on the grounds beside the Rua do Recolhimento.

In 1998, the semi-rectangular spaces, columns and cistern were adapted into the museum ''Olissipónia''. On 22 August 2006, Direcção Regional de Cultura Lisboa (DRCLisboa) defined a special protection zone, that included the Castle of São Jorge and the rest of the walls of Lisbon, the ''Baixa Pombalina'' and various properties that were already classified as cultural heritage. The ''Conselho Nacional de Cultura'' (National Council of Culture) proposed shelving this definition on 10 October 2011, which was supported by IGESPAR.
