I went to Smailholm Tower with my family. I counted all the big bricks from the bottom all the way to the top, there were about 80 bricks. I also counted the big bricks all the way across which was about 104. We then used Daddy's phone to times together 80 and 104, the answer was 8,320. We then multiplied that by 4 as there are 4 sides of the tower which are nearly the exact same. So my estimate is there are 33,280 big bricks at Smailhom Tower.
