Graus had been the capital of the region, and old opulence in buildings remains. This fine hotel, Hotel Del Palacio Obispo, Palace of the Bishop, is at the historic district, and offers glimpses of the past in its 15th Century structure.
The elephant may refer to Hannibal who, in the Second Punic War, led his elephants across Hispania to get to Rome, see http://en.wikipedia.org/wiki/Military_history_of_Spain/. Is that a turbaned head, lower left? that could refer to the era of Moorish occupation. The official coat of arms for Aragon also shows a turbaned head, with side ties hanging down. Do search in Images for Aragon or Huesca or Graus coats of arms.
This appears to be rustication as well as original rubble and rock and mortar, but an expert would have to examine.
Now, back to our room. Elegant.
Applaud the repurposing of this historic 15th Century structure, the Bishop's Palace, Palacio del Obispo. For road trippers, the added advantage to having such fine accommodations, is the parking. Right across the street.
There are other hotels, including the Hotel Lleida, but we wanted to be closer to the old parts, away from busses.
