Heath Flor builds a replica of Smolny Cathedral in St. Petersburg, Russia. It took Heath almost a year to plan and build it, and he used between 20 and 30 thousand bricks to complete it. This is his largest project so far, and I must say it was truly worth the effort! It is simply amazing. With large projects like this, it is not only the beauty of the model we need to admire, but also all the time, effort and patience needed to complete it.
