Timelessly magnificent, limestone can be found throughout the world’s most famous structures, such as Egypt’s Great Pyramid, and many historical cathedrals and churches across Europe. Limestone originally starts as shells, mollusks, and marine animals millions of years ago, and brings a truly unique natural quality to your home. Limestone is frequently used for flooring in bathrooms, fireplace facades, kitchen backsplashes, as well as indoor or exterior applications. Even when brought to a high polish, limestone retains a beautiful organic texture. It is not uncommon to see numerous well-preserved fossil impressions imbedded beneath the surface making limestone an excellent choice for areas in your home that you want to showcase such as the fireplace in a living room or master bedroom. Limestone was also a very popular building block in the Middle Ages in the areas where it occurred, since it is hard, durable, and commonly occurs in easily accessible surface exposures. Many medieval churches and castles in Europe are made of limestone. Acid-based cleaning chemicals can also etch limestone, which is why it should only be cleaned with a neutral or mild alkaline-based cleaner and not an acidic one.
