You’re standing on a street corner in Baltimore, phone in hand, looking for the "Weinberg Building." You see a brick facade in the distance. You start walking. But wait—are you at Johns Hopkins? Or are you at the University of Maryland Medical Center? Or maybe you’re actually looking for the Weinberg Center at Mercy?
Honestly, it’s a mess for GPS apps.
Baltimore is home to several massive medical facilities named after Harry and Jeanette Weinberg. The Weinberg Foundation has poured hundreds of millions into this city, and as a result, their names are plastered on some of the most critical healthcare infrastructure in the Mid-Atlantic. If you have an appointment at the Weinberg Building Baltimore MD, you need to be 100% sure which campus you’re headed to, because they are miles apart in some of the city's heaviest traffic.
The Big One: The Harry and Jeanette Weinberg Building at Johns Hopkins
Most people searching for this keyword are looking for the clinical heart of the Sidney Kimmel Comprehensive Cancer Center. Located at 401 North Broadway, this is a beast of a building. It’s roughly 500,000 square feet. To put that in perspective, that’s about nine football fields worth of space dedicated almost entirely to cancer care, surgery, and intensive care.
When it opened around the turn of the millennium, it was a game-changer for Hopkins. Before this, cancer services were scattered all over the sprawling East Baltimore campus. Now, it’s a "one-stop shop" for oncology.
What’s actually inside?
It’s not just a bunch of doctor offices. This building is high-stakes.

- Operating Suites: There are 16 of them. These aren't for routine stuff; these are for complex oncology and transplant surgeries.
- Inpatient Beds: About 62 beds are dedicated to medical oncology (think chemotherapy and bone marrow transplants), plus another 72 for surgical recovery.
- The ICU: There are 20 intensive care beds here.
- The "Smart Card" System: Hopkins was early to the game with tech. They use a registration system that tracks you through your appointments so you aren't stuck repeating your name and birthdate 50 times to 50 different nurses.
The vibe inside is surprisingly quiet. They actually banned overhead paging. You won’t hear "Doctor Brown, extension 402" blaring while you’re trying to rest. Instead, staff wear infrared badges that let the unit clerks find them silently. It sounds small, but if you’ve ever spent a night in a hospital, you know that silence is a luxury.
The Downtown Rival: Weinberg Building at UMMC
If your GPS took you to 22 South Greene Street, you are at the University of Maryland Medical Center (UMMC). This is the other Weinberg Building.
This one is the anchor for the downtown campus. It’s the home of their Emergency Department—which is a big deal because UMMC handles some of the most intense trauma cases in the state.
Inside the UMMC Weinberg Building, you’ll find:
- A massive 24-hour pharmacy (super helpful if you’re discharged late at night).
- The Women’s and Children’s Center.
- State-of-the-art obstetrics facilities.
- A seven-story glass atrium that actually makes the place feel less like a hospital and more like... well, something modern and breathable.
The architecture here by Perkins & Will (with Design Collective) won awards back in 2004 because it managed to fit 375,000 square feet into a very tight urban "street wall" along Lombard Street. It’s a masterclass in urban planning, even if it’s a headache to park near.
The Third Contender: Mercy Medical Center
Just to keep you on your toes, Mercy Health Services also has the Weinberg Center for Women’s Health & Medicine.
This is located at 227 St. Paul Place. If you are looking for specialized breast cancer treatment or gynecological oncology, there’s a good chance this is your actual destination. It’s a 120,000-square-foot facility that focuses heavily on a "hospitality" feel. They even have a custom waterfall memorial in the lobby.
It’s easy to see why people get confused. All three buildings focus on cancer, all three are in Baltimore, and all three carry the Weinberg name.
Who were Harry and Jeanette anyway?
You can't talk about these buildings without mentioning the money behind them. Harry Weinberg was a guy who basically built a transportation empire. He owned bus lines in New York, Dallas, and Honolulu.
He grew up poor in Baltimore, selling souvenirs on the street when he was ten years old. He never forgot that. When he died in 1990, he left almost everything to his foundation. Today, that foundation has billions in assets. They don't just put names on buildings for ego; they do it because they provide the "gap" funding that lets these hospitals build things the state or the universities can’t afford on their own.
Interestingly, the Weinberg Foundation doesn't actually own these buildings. They give the grant, the hospital builds it, and the hospital runs it. If you have a billing issue or a complaint about your room, don't call the foundation. They just paid for the bricks.
Survival Tips for Your Visit
If you are heading to the Johns Hopkins Weinberg Building specifically, there are a few things you should know that aren't on the official "About Us" page.
The Security is Real
You have to go through a weapons-detection system. It’s a "weapons-free" campus. Don't be surprised by the lines at the North Broadway entrance during peak morning hours.
Parking is Underneath
The Hopkins building has three levels of underground parking. This is a lifesaver. If you are a patient, you can often take an elevator directly from the garage to the lower level where radiation therapy is located. It saves you from having to walk through the main lobby when you’re not feeling your best.
The Juice and Java Cafe
It’s in the lobby. It’s basically the social hub of the building. If you’re a family member waiting for a surgery to finish, this is where you’ll spend your time.
The Bridge Connection
The Weinberg Building is connected to the main Johns Hopkins Hospital by a glass-enclosed walkway. If you get lost—and you will, because Hopkins is a labyrinth—look for the signs for the "Zayed" or "Bloomberg" buildings. The Weinberg Building is the gateway to the older parts of the campus.

What Most People Get Wrong
The biggest misconception is that the Weinberg Building at Hopkins is just for "rich" patients or international "VIPs."
While it’s true that people fly from all over the world to see surgeons here, the building was specifically designed to handle the high volume of Baltimore locals. They serve about 400 patients a day. It’s a workhorse, not a museum.
Another mistake? Assuming every "Weinberg" building is the same. I've seen people show up at Mercy for an appointment that was actually at UMMC.
Double-check your paperwork. Look for the street address:
- 401 N. Broadway = Johns Hopkins (Cancer focus)
- 22 S. Greene St = UMMC (Emergency/Women's focus)
- 227 St. Paul Pl = Mercy (Women's Health focus)
Actionable Steps for Patients
- Verify the Address: Before you leave, check if your provider is part of the "Johns Hopkins University" or "University of Maryland" system.
- Download the App: If you’re going to Hopkins, use the MyChart app. It usually has the exact building and "wayfinding" instructions built in.
- Arrive 45 Minutes Early: Between the Baltimore traffic, the parking garage navigation, and the weapons screening, you will lose 30 minutes before you even reach the check-in desk.
- Ask for a "Smart Card": If it’s your first time at the Hopkins Weinberg Building, ask how to get your registration card to speed up future visits.
- Use the Tunnels: If it’s raining or snowing, use the underground tunnel system that connects the Weinberg Building to the rest of the Hopkins campus. It’s climate-controlled and much safer than crossing Broadway in a storm.
