There are many building materials that make up the Washington Monument.Structurally it is made of Bluestone Gneiss. The outer facing stones are marble. The commemorative stones include: granite, marble, limestone, sandstone, soapstone, and jade.Due to the 20 year hiatus in construction when the monument was only 150 feet tall, the bottom and top sections are slightly different colors.
