Go all the way around the Alcazaba, going up Cava Street. Go straight on along Graciano Street and Oviedo Street. In the Plaza Miguel Angel Blanco, you will see on your left the entrance to the Mithraeum House (Casa del Mitreo). Walk the full length of the footbridge, covering the entire rectangular space and pause to view the most significant mosaic, the so-called the mosaic of the Cosmos.
