The City of Pueblo has a long and colorful history dating back to 1842, when it was called Fort Pueblo.
What brought our city from a small fort in southern Colorado to the backbone of Colorado were the ore mines.
This area once housed 4 separate towns, which are Pueblo, South Pueblo, Central Pueblo, and Bessemer. These 4 towns together now make up the City of Pueblo.

The Williams Seed Store is located on the southeast side of Hwy 50 in Pueblo County. The Williams family has farmed on the land since 1913 and operated the seed store since Guerino “Henry” Angelo Williams opened it in 1936.
During its prime, the Williams Seed Store produced corn, asparagus, tomatoes, squash, and chiles among other crops with the purpose of harvesting through all seasons
Additionally, the seed store was instrumental in supplying seeds and starters to farmers and residents in the surrounding region.
The building is also significant as an Italian owned and operated farm
After immigrating in 1892, Henry’s parents, Angelo and Giuseppina Guglielmo, arrived in Pueblo in 1894 and changed their last name to Williams in 1906.
Henry and his wife originally purchased the property from his parents for $1.00 in 1928. In 2024, it was added to the State Register of Historic Places!

Longest-Running Food Establishments
While some are markets with delis, they represent the oldest continuous food operations in the city:
Gagliano’s Italian Market
Operating at its current address since 1921, this is arguably the oldest food-related business in Pueblo. It evolved from a neighborhood grocery into a landmark deli known for its homemade Italian sausage and specialty breads like “stro”.
The Senate Bar & Grill
Established as “The Senate” in 1939, it is recognized as one of the city’s oldest taverns. The building itself dates back to 1904 and even survived the devastating 1921 flood.
Shamrock Brewing Co
Originally opened as the Shamrock Café around 1940, it has been a downtown staple for over 80 years. It still features its original vintage mahogany bar and a World War II-era tile floor.
Ianne’s Pizzeria Inc
Founded in 1945, it is celebrated as the oldest pizzeria in Colorado. Now in its fifth generation of family ownership, it continues to serve original recipes in the historic Bessemer neighborhood.
Pass Key Restaurant
A Pueblo icon since 1952, it began as a drive-in purchased by the Pagano family. It is famous for the “Pass Key Special,” a unique square Italian sausage sandwich.

Sweeny Feed Mill
Sweeny Feed Mill, shared by Keith Guererro on Facebook, May 19, 2026
The property at 403 E 4th Street in Pueblo, Colorado is historically known as The Sweeny Feed Mill.
It is an officially designated Pueblo Local Landmark, receiving its formal historic status on August 26, 2006.
Historic Pueblo
Historical Significance
* Industrial Heritage: Built between 1896 and 1897, the mill represents the agricultural- and extraction-based processing industries that once drove Pueblo’s growth as Colorado’s principal industrial center. These types of historic industrial facilities are now increasingly rare in the city.
* Prominent Figures: The building’s history is closely tied to its prominent early owner Andrew McClelland, manager Joseph F. Sprengle, and James Koller Sweeny.
* Historic Pueblo�Architectural Highlights
* Curtain Wall Innovation: The main 3-story brick storefront is highly unique for its era, serving as an early example of industrial “curtain wall” construction. It utilizes minimal structural components throughout the building rather than traditional heavy masonry or wood framing.
* The Crib Tower: The adjacent 3-story grain and hay elevator tower (added around 1900) features “crib” construction. This distinct engineering style consists of flat-stacked 2-by-6-inch boards to withstand the heavy internal pressure of stored grain.
* Interior Character: The interior retains massive historic appeal, featuring exposed brick and timbers, high ceilings, large windows, and original loading docks.
* Historic Pueblo Current Status
The complex encompasses roughly 18,522 square feet of space sitting on a 0.44-acre lot right near Downtown Pueblo and the Fountain Creek area. Because of its industrial (I-3) zoning and landmark status, the City of Pueblo actively encourages its adaptive reuse and preservation, leaving the door open for future conversion into a brewery, distillery, creative gallery, or unique loft apartments.
If you are exploring the genealogy or local architecture of 403 E. 4th Street, a treasure trove of historical connections links the property to Pueblo’s growth.
Historic Pueblo
Genealogy & Family History Context
Three primary figures shaped the history of the mill:
Historic Pueblo
* Andrew McClelland (The Entrepreneur/Owner): Born in Missouri, McClelland moved to Pueblo in 1882 to start a wholesale grain and feed business. He was a massively influential Pueblo figure; he founded the Pueblo Free Public Library (which was named after him), built the Columbia Heights subdivision, and brought the Missouri Pacific Railroad to town. In 1904, he took a trip around the world and brought back artifacts—including an Egyptian mummy—that are still displayed on the top floor of the Rosemount Museum.
* James Koller Sweeny (The Namesake/Manager): Born in Baltimore, Maryland, in 1856, Sweeny moved west and married Rose Belle Crystal in Pueblo in 1880. He took over operations at the mill, establishing it as a multigenerational business. The Sweeny Feed Mill operated at this exact location for well over 100 years, continuing to manufacture feed here until high utility costs forced the business to close the historic physical mill.
* Joseph F. Sprengle (The Early Manager): Sprengle worked alongside McClelland to build up the early distribution and agricultural processing infrastructure that turned Pueblo into a regional industrial hub.
Architectural Significance
For architecture enthusiasts, the building is a masterclass in turn-of-the-century engineering:
City of Pueblo, CO
* Union Avenue Style Influence: While located on 4th Street, its design complements the commercial aesthetic of the historic Union Avenue area. The brick exterior features stone piers, spandrel accents, and large windows intended to maximize interior daylight.
* Pioneering Curtain Wall: Rather than relying on standard thick, heavy masonry or bulky internal wood framing, the building utilized an early form of industrial curtain wall construction. It relies on highly distributed, minimal structural components to maximize usable open floor space.
* Cribbed Grain Elevator: The 3-story grain/hay storage tower built in 1900 features a rare “crib” building technique. It is constructed entirely of flat-stacked 2×6-inch boards. This layering allowed the wood walls to flex slightly and absorb the intense outward lateral pressure of thousands of pounds of loose grain without bursting.
* Sweeny Feed West in Pueblo West was historically a separate business from the original Sweeny Feed Mill in Pueblo, though both originated from the same family.

Mesa Junction
The oldest neighborhood in Pueblo, Colorado is Mesa Junction (originally part of the independent town of South Pueblo), and Abriendo Avenue was absolutely one of the very first and most critical thoroughfares established in the city.
The History of Mesa Junction & Abriendo Avenue
Before Pueblo consolidated into a single city in 1886, the area was divided into four separate rival towns: Pueblo, South Pueblo, Central Pueblo, and Bessemer.
The Trolley Hub: The historic neighborhood of Mesa Junction sits at the heart of what used to be South Pueblo. The name “Mesa Junction” originated because the intersection of Abriendo Avenue, Colorado Avenue, and Broadway served as the central interchange for Pueblo’s extensive old streetcar and trolley system.
One of the First Retail Centers: Because the trolley system brought lines together at this specific point, a commercial district naturally exploded around it.
Today, this century-old business area along Abriendo Avenue is celebrated as one of Colorado’s oldest retail centers.
Historic Architecture: Because it is one of the city’s earliest developed areas, you will find incredibly diverse architecture there.
The neighborhood features grand Victorian mansions and early 20th-century bungalows. Many of the side streets are distinctly wide because they were originally laid out to accommodate the passing streetcars.
Iconic Historic Landmarks on Abriendo AvenueIf you explore Abriendo Avenue today, you are walking directly through Pueblo’s deep history. Some of its most iconic landmarks include:
My Grandparents lived on Olney Ave. and we would walk to Chet’s Grocery Store known today as Renewed Wholesale (720 S Main St):
Situated right at the intersection of S Main St and E Abriendo Ave. They carry an eclectic, rotating collection of both new and lightly used furniture, including dressers, entryway tables, and leather reclining couches.
