Ah, you'll have to travel to get the rest, so that I may maintain my doctor-patient confidential relationship!
Seriously, this hotel is very close to Sintra, as well. Sintra has the Palacio de Pena, which is situated on top of a mountain. It is only about two hundred years old, but beautiful with its Arab influences in architecture.
Here are some pictures:

The older castle is about 500 meters downhill from it, and is much older, almost 1000 years. It is just ruins, now.

We haven't had a chance to go through our pictures yet, but I will try and take care of it when I get home.
