More about the castle, but not all
It really started with an Italian architect who fell in love with the daughter of the mayor of Lamas. She wouldn´t marry him if he wouldn´t build her a castle. It took 5 years to finish it. By then the pretty girl wasn´t pretty anymore and had run off to Tarapoto. But her father, the mayor stayed in good terms with the architect... This of course if fantasy with just a little bit of truth.
