Mula offers the visitor aged palaces and monuments displaying the wealth that the Marquis de los Vélez invested in safeguarding his position against the local populace when he erected his imposing castle, a magnificent 16th-century construction dominating the plain below and which gives he impression of having simply emerged from the very rocky outcrop on which it perches. The town itself has a great deal of charm, spreading out as it does, from around the Plaza Mayor, in which the church of San Miguel is of note.
