 The core of the district runs the length of First, Second, and Third Streets, between "C" and "M" Streets and includes many types of architecture from the 1850s to the present.Though not officially within the district, the Carson Mansion, the undisputed Victorian jewel of the city and region, commands the highest elevation at the eastern edge of the district.Art venues, coffee shops, bed and breakfasts and inns, antique stores and shops, restaurants, museums and galleries, and public areas (complete with views of Humboldt Bay and its marinas) are among the highlights of this gem of the West Coast.
