Parador de Sigüenza
This fairy-tale 12th-century castle has hosted royalty for centuries, from Fernando and Isabel right up to Spain's present king, Felipe VI. Some guest rooms have four-poster beds and balconies overlooking the wild landscape. The stellar food served here is an essential part of the experience; at a leisurely lunch, your choices might include roast goat, pheasant, or cod with truffles and sheep's cheese.
