It is located on Paseo del Espolón opposite the Teatro Principal. It has a magnificent classicist façade with three entrance doors. Over the main entrance there is a decorated balustrade with four ionian pillars with a classic pediment.
Inside there is an imposing imperial staircase whose skylight is decorated with wall paintings by Vela Zanetti. These paintings from 1965 represent four scenes from the poem Cantar del Mio Cid: “La Jura de Santa Gadea”, “El Destierro”, “la Batalla” y el “Duelo”.
