The most photographed monument in Andorra is the dam and guard's house of Ràmio with 47 photos by 2 participants. It has no article. Not an impressive number, but it is interesting that it is also the most remote monument of Andorra. The two guys walked an hour to reach it through the World Heritage Site of Madriu Valley. It worths taking a long rest and they had time to take more shots than in other sites :-)
