I have to apologize - print a retraction. Apparently the Cathedral of Madrid - Nuestra Senora de la Almudena was started in the late 1800s and finished, after delays from wars and loss of funds, in 1993.
Camillo ask the man running the elevator to the Cupola for some information, and was given 'bogus information' about the construction. To compensate for my lack of correct detail, I am including some additional photos of the cathedral. ginger v
