That is awesome! I’m forwarding it to my 15 year old grandson. When he was little age 3 and up, he and I would spend hours creating some intricate Lego and K’nex creations. He could look at the instructions and figure out from the diagrams what steps to take. My job was to provide him with the correct number of pieces for each step. He would tell me, “Nana I need this piece next.” I enjoyed the interaction and conversation with him that building those creations provided. He will get a kick out of seeing the Vatican in Legos. That’s an impressive and time consuming hobby. I liked the cathedrals too. Too bad COVID19 has put so many events on hold. I would travel to go see something like that.
