One day
Start on the Plaza Mayor with a coffee, climb the Torre de Bujaco for the view, then pass through the Arco de la Estrella into the Ciudad Monumental. Wander the palaces and towers, the Plaza de Santa María and the co-cathedral, and the old Jewish quarter, looking up for the storks. Have a jamón-and-cheese tapas lunch, see the Cáceres Museum and its Moorish cistern, and return after dark for the floodlit walled town.
