Yes, the Crystal Palace in El Retiro park, which looks particularly nice in late November. I'll indulge myself with one more snap of the Palacio de Cristal, which was built as @stagor hinted for the Phillippines Exhibition of 1887.Madrid? Palacio de cristal??
I must have a good memory for photographs, I drove from Bolzano up to the Brenner Pass this year. Stunning scenery.A lovely place tho - spent a fortnight there last year. Lots and lots of great scenic walking.
