Most of Silverton sits inside a National Historic Landmark district

Much of the town of Silverton is a National Historic Landmark district recognized for its mining-era buildings, which is worth knowing if you own or change a property there.

Published June 10, 2026 - Last verified June 11, 2026

Silverton is more than an old mining town in spirit. Much of the town is a recognized National Historic Landmark district, designated for its tie to the settlement of the western frontier and the growth of metal mining in the San Juans. The district takes in most of the original townsite and the masonry, commercial, and residential buildings that give Silverton its late-1800s look.

For a visitor, that mostly explains why the streetscape feels so consistent and old. For someone who owns or hopes to buy property in town, it can matter more directly. Historic recognition does not freeze a building in place, but changes to a designated property can come with extra review, and there may be both benefits, like preservation programs, and added steps. The rules that actually bind a specific parcel come from local zoning and any preservation ordinance, not from the landmark label alone.

If you are weighing a building inside the district, it is worth asking the Town of Silverton early what applies before you plan exterior work.

To understand the district’s boundaries and significance, History Colorado and the National Park Service landmark records are the reliable sources, and the Town of Silverton can confirm what governs a given address.
