The Early Years: Victorian and Romanesque Revival

In the late 19th and early 20th centuries, Denver experienced rapid growth, fueled by the mining boom and its strategic location as a transportation hub. This period saw the rise of several architectural styles that still leave their mark on the city today, such as Victorian and Romanesque Revival architecture.

Victorian Architecture

During the late 1800s, Denver was heavily influenced by Victorian architecture, which was known for its ornate details, steep rooflines, and intricate woodwork. One of the most notable examples of Victorian design in Denver is the Molly Brown House, located in the Capitol Hill neighborhood.
