The first challenge this year has been won by... David, Ana and Micaela! Congratulations! You have won a positive mark each.
The answer was: The Palatine Chapel, built by Charlemagne during the 8th century in his Palace in Aachen, capital city of the Carolingian Empire.
Tomorrow we will have the second challenge!
Reminder: To participate in the challenge you have to comment HERE in the blog, in the blog comments, choose the option anonym if you don't have a google account and sign your comment with your name.
