Southeast, in the fort's former arsenal, is the regional Parlament de Catalunya. You can join free guided tours, in Catalan and Spanish (Castilian) only, on Saturdays and Sundays; sign up online in advance. The building is open for independent visiting on 11 September from 10am to 7pm. Most interesting is the sweeping Escala d’Honor (Stairway of Honour) and the several solemn halls that lead to the Saló de Sessions, the semicircular auditorium where parliament sits.

At the centre of the garden in front of the parliament is a statue of a seemingly heartbroken woman, Desconsol (Distress; 1907), by Josep Llimona.
