Stone workers and stonemasons have created buildings, monuments, roads, and many othe types of structures since before the existence of civilization. Examples of stone work and stonemasonry can be found world wide. It utilizes a number of different types of stone and methods for creating foundations, walls, and covernings on buildings. Modern stonemasons learn their craft by serving an apprenticeship and they learn how to measure, cut, and install stone materials by using both hand tools and pneumatic power tools. The Minnesota State Captiol building was largely built by stone workers who used steam powered saws and polishing machines, and hand tools. Stone finishers were a specialized group of stone workers who precisely trimmed blocks of stone with an adz or a hammer and chisel. They could also be found carving details into stone statuary.
There are numerous photographs on this website that show stonemasons, stone materials, and the tools that were used in the Capitol construction. For other information about stonemasonry and stonework see:
