Founded in 1859 by gold seekers from Kansas and Georgia, Denver marks the boundary between the Great Plains and the Rocky Mountains that provide a splendid backdrop. A university town and the capital of American craft beer, it is called the 'Mile High City' because it is located exactly one mile (about 1600 meters) high, as noted on the 13th step of its Capitol building. Modern and youthful, it has trendy neighborhoods for all tastes and is pleasant to explore on foot, featuring diverse architectures ranging from Victorian to postmodern, along with art, history, culture, shopping, and a vibrant nightlife.
