identify a flowering tree in Spain

I was traveling in Spain in September, and at the entrance to the Alcazar in Seville I saw a mgnificent flowering tree. It was mature, it had a round crown about forty feet tall and wide, and it was covered with large pink-and-white flowers that looked like clematis or passion flowers. I did ask about it, but I did not understand the Spanish answer and had no way to write down the name. Can anyone tell me what this tree is? Blooms in September (at least), large, rounded crown, large flowers (about four or five inches) resembling passion flowers or clematis covering the tree like a blanket, deep pink with white center or band down the center of the petals.
The flowers are similar to those of Chorisia Speciosa, but the trunk was not anything like that kind of trunk. The trunk and branches were more like those of any typical garden tree, for instance like a very old common Norway maple.
Thank you for any suggestions.

 

Did you get a picture of it because that helps alot when identifying

 

No, I did not, except one from a great distance that is of no help. Sorry. It was one of those moments that I was just not prepared.
But it was SO EXTRAORDINARILY BEAUTIFUL that I would love to identify it. I am sure I cannot grow it here on Long Island, New York, USA, but in case my fantasy of a home on the Mediterranean ever comes true, I want to know what this tree is!
Thank you, Blake, for answering so quickly.
We will solve this!

 

Here is the photo from a distance:

Sorry, that doesn't work! See the info here on Attaching Images.

 

As far as can be seen from this distance, trunk of specimen on right looks like Chorisia.

If the flowers looked just like those of Chorisia, then it would be that or perhaps a related genus.

 

I will try to figure out how to attach the photo./Users/clydewachsberger/Pictures/iPhoto Library/Originals/2008/Espana 2008/P1020297.JPG

 

It still didn't work. try on the (where you post) press go Advanced, press attachments, press brouse then look for the picture. Then when you find it press upload. If it is on a site put it where the stars are.

Heres an example of a picture: (there moon flowers)

 

Thank you, Blake. I will try to attach the photo this evening when I get home.

 

Could be Chorisia or the closely related Ceiba as well. Definitely something in the Malvaceae, given the flower structure you're describing.

 

The picture I linked to shows flowering trees in the same location - surely they are the ones you asked about.
