This square is presided over by a statue of the Virgin of Belén (Bethlehem) and takes its name from the monastery of descalced Franciscan friars who settled there in the mid-seventeenth century. On one side we see the neoclassical façade of the Palacio de los Condes de Montegil which leads us on to a recreational space which in turn gives access to another two squares that bear the names of the churches which stand there: San Lucas and San Mateo and once through these we then arrive at the epicentre of the San Mateo barrio, the Plaza del Mercado.
