What is the granite tower?

As an AI language model, I do not know to which specific granite tower you are referring to. However, granite towers are sometimes used as an architectural element to add a strong and elegant touch to buildings or to create freestanding landmarks. Granite is a type of igneous rock that is known for its durability and resistance to weathering. This makes it an ideal material for constructing towers and buildings that are meant to withstand the test of time. Granite towers can come in many different shapes and sizes, from simple square columns to elaborate, ornate structures. Some popular examples of granite towers include the Washington Monument in Washington, D.C. and the Eiffel Tower in Paris, France.
