National Ballpark Museum
“less museum visit, more living history seminar with an obsessive”
One block from Coors Field, tucked into a 1,500-square-foot LoDo storefront, sits the only museum in the world dedicated exclusively to the classic ballparks — Fenway, Ebbets, Forbes, the Polo Grounds, and eleven others. Founder Bruce "B" Hellerstein spent the 1980s stashing bricks, turnstiles, light fixtures, and stadium seats in his basement before landing this space in 2010; Smithsonian Books has since ranked his collection among the top 20 finest private baseball collections on earth. The catch: there's a phone number on the door, you call it, and Bruce himself appears to walk you through every relic personally — it's less museum visit, more living history seminar with an obsessive. Denver's actual top-ten lists are full of Red Rocks and the Mint; this one stays resolutely off them, which is exactly the point.
The story
In the 1980s, long before major league baseball arrived in Colorado, a Denver CPA and third-generation native named Bruce "B" Hellerstein started filling his basement with pieces of demolished American civic cathedrals. While standard collectors chased autographed cards and game-worn jerseys, Bruce went after structural hardware: cast-iron seats, light fixtures, bricks, and turnstiles salvaged from the 14 "classic" ballparks built during baseball's Golden Age between 1909 and 1923. In 2010, he finally migrated the hoard out of his house and into a 1,500-square-foot storefront on Blake Street—a scant 315 feet from Coors Field's main gate [1.2.4]. Smithsonian Books eventually ranked it among the top 20 finest private baseball collections on earth, but if you aren't looking closely, you'll walk right past it.
You enter the museum by pushing through an authentic 1909 working turnstile from Philadelphia's Shibe Park. Inside, the narrow walkways feel deliberately tight, mimicking the cramped urban footprints of long-gone stadiums hemmed in by city blocks. The space is packed to the ceiling with improbable relics: a piece of the original copper facade from Yankee Stadium's third deck (one of only two known to survive), a light fixture from Ebbets Field's marble rotunda, and original wooden seat sets from all 14 classic parks. Bruce didn't forget local history either; tucked alongside the major league artifacts are vintage seats and memorabilia from Denver’s forgotten minor league sanctuaries, Merchants Park and Bears Stadium.
What it's like
Stepping inside feels less like visiting a formal museum and more like stepping into the personal den of an obsessive archivist. If the door is locked or the lights look dim, don't walk away—check the front glass for the phone number. Give it a dial, and Bruce or a dedicated volunteer will usually appear to unlock the space and walk you through the collection personally, detailing the backstory of every piece of salvaged cast iron. Expect tight aisles, the faint smell of vintage leather, and deep-cut stadium trivia. Skip Rockies game days when LoDo gets choked with parking surges and stadium crowds; come on a quiet weekday afternoon so you can sit in a Fenway or Polo Grounds seat uninterrupted.
The move: Call ahead (303-974-5835), show up on a weekday, and let Bruce give you the full founder-led tour — then grab a beer at one of the LoDo bars on Blake Street and debate which demolished ballpark you'd most want back.
📍 Before you go It's a small storefront at 1940 Blake St, one block up from Coors Field in LoDo — easy to walk past, so look for the entrance and step through the old turnstile. Admission is free, but it keeps limited days (closed some weekdays, and hours shift between baseball season and the offseason — check ahead). The collection is small and the guided walkthrough is the whole draw, so go when someone's there to lead it; quiet weekdays beat Rockies game days, when LoDo parking and crowds surge. Pair it with a game, the Blake Street bars, or Union Station nearby.
