A favourite. Castle on the coast with rampart walk down into the town with many seafood restaurants as well as good seafood in the parador restaurant.
Benavente
Castle next to "balcon" paseo, ground floor rooms adjoin pool.
Cáceres
Beautiful palace in middle of historic walled old town.

Hotel Atlantico is wonderfully placed to explore old Cadiz.

Palace close by the sea.Ideal for sampling wine and seafood from the Rias Baixas area.Cambados has a market on Saturday where you can sample local cheese and ham.

Ex monastery set in spectacular mountain area.

Located in the caldera of the old volcano. Exceptional unpolluted night sky and views of Teide.

Not an historic buliding but one of the several mountain lodge style paradors situated in mountain areas.

Castle surrounded by extensive city walls, which make a great paseo.
Cuenca
Situated with perfect view of the hanging houses.
Chinchón
Near the charming town's Plaza Mayor with an elegant restaurant.
El Hierro (modern)
Beachside, on the east coast.
Granada
Surpassed only by Santiago, this parador is set in the grounds of the Alhambra, in summer outdoor dining with guitar accompaniment and views of the Generalife  not to be missed. 
Guadalupe
Next to the monastery, beautiful interior patio and walks through the old town with its houses upper floors supported by wooden rather than stone columns.
Hondarribia
Cleverly restored castle, bed and breakfast only.
Jaen
Stern castle, possibly the most impressive parador castle, strangely never quite works for us.
Jarandilla de la Vera
Castle-palace with unusual stonework.
Leon
Five star grand lux to rival Santiago in theory but not in practice for us.
Lerma
Classic castle on town square with a few of its (non standard) rooms eccentrically squeezed into turrets. Wonderful atmosphere in lounge and restaurant.
Limpias
Palace set in woodland with modern extension.
Malaga Gibralfaro
Small parador in dramatic location above Malaga. Modern rooms but ajoining castle. Malaga golf is a modern parador very close to the airport.
Merida
There is a arabic flavour to this parador convenient for the impressive Roman ruins. 
Montforte de Lemos
Hilltop palace above modern town with ajoining castle that may be visited. Some rooms in modern extension to rear.
Olite
Fascinating complex castle with parador in a wing.
Oropesa
Palace parador with adjoining castle.
Plasencia
15th century convent parador in walled city. Do not miss the "bar de la noche" for an extravagant (in all senses) late night drink.
Pontevedra
Manor house situated in the centre of old Pontevedra
Ronda (modern)
Set between the famous bridge and the bullring.
Santiago
Former royal hospital, set around four interior patios and next to the cathedral in the town square which is the destination of the many pilgrims and walkers taking the "Camino de Santiago". Five star grand lux. 
Santillana del Mar
No longer on the coast, the town's parador is now in two charming building around a square.
Santo Domingo de la Calzada
12th Century hospital with beautiful interior.

A modern parador in a stylish design overlooking the old town
Seu d'Urgell
Modern Parador bulit round ancient colonade in superb location beneath Pyrennees. Charming small old town with 1992 Olympic kayak course.
Siguenza
Hugely impressive castle in quiet town still bearing scars of civil war. Stately public rooms.
Sos del Rey Catolico
Birthplace of Ferdinand in Navarre, this small town is partly restored and partly undergoing restoration.
Tortosa 
10th Century castle in commanding position in town near Ebro delta. In 2006 looking a little frayed at the edges and I have to say the restaurant service, while willing, has not been up to normal standard on our two visits.
Trujillo
16th Century convent in fortified town with large castle. Look out for an example of the revolving doors that nuns use to sell sweets to the public.
Ubeda
Impressive palace with interior courtyard.
Vilalba
Originally contained in a tower with charming curved rooms, this Parador has been extended since our last visit.
Zafra
The palace castle of Hernan Cortez near the interesting linked double main squares of the town, Plaza Chico and Plaza Grande.
