The remaining part corresponds to the southeast nave, the oldest of them all. The facade facing the cathedral shows the defensive function of the building, while overlooking the courtyard, with its windows and gates, we see its role as a residence and housing.
The conserved nave is the result of a renovation of the pre-existing Andalusian buildings. Originally, it was covered by a wooden roof that before 1244, as recorded in the Llibre dels Feyts from James I the Conqueror, was replaced by vaults, of which only the corbels and the start of the ribs are preserved. These vaults were dismantled in 1926 due to the danger of their collapse on the nave of the patio. The only element that remained of the Gothic building of the palace was lost.
The nave that can be visited today now has a roof terrace that is accessible to everyone, where you can admire the nearest and farthest landscape. From the terrace, the hill, the river, the irrigated land, all become distinctive elements of Lleida. It also confirms the position of the castle in relation to a territory, which was and is its capital.
