Superheroes are everywhere you look these days—and if you're in the right city, the same can be said for their favorite meeting spots. From Avengers Mansion to the Super Friends' Hall of Justice, many of the homes, headquarters, and hangouts of comics' most famous icons were inspired by real-world locations. Here are some of the most notable heroes' headquarters that have served double-duty in both comics and the real world.

1. Avengers Mansion

First appearing in 1963's Avengers #2, the mansion that Iron Man, Thor, Hulk, and the rest of “Earth's Mightiest Heroes” called home is located at 890 Fifth Avenue in the Marvel Universe's version of Manhattan. Here in the real world, that address corresponds to the Henry Clay Frick House (above and top), a massive mansion that occupies much of the city block where Fifth Avenue meets East 70th Street, and now serves as a museum. Avengers co-creators Stan Lee and Jack Kirby modeled the superhero team's mansion after the Frick House, which Lee passed each day on his commute.

2. The Sanctum Sanctorum

The lair of Marvel's sorcerer supreme, Doctor Strange, is located at 177A Bleecker Street in the Greenwich Village neighborhood of Manhattan. Often at the center of various magical goings-on in the Marvel Comics universe, the real-world apartment building at that address is significantly less impressive—though it does have a notable connection to the comics world. In the 1960s, Marvel Comics writers Roy Thomas and Gary Friedrich shared an apartment at 177A Bleecker, which explains how the address eventually found its way into comics canon. (The fact that there's now a Pinkberry Frozen Yogurt shop on the ground floor of 177 Bleecker is a detail the comics seem to have ignored, for some reason.)

3. The Hall of Justice

Anyone who grew up watching the feel-good animated adventures of Hanna-Barbera's Super Friends will recognize the unique architecture of the Hall of Justice, the headquarters for Superman, Batman, and the rest of the DC superheroes featured in the program. The unique art-deco style of the building was inspired by the Union Terminal in Cincinnati, Ohio—a former train station that now serves as a museum and library. A background supervisor on the series, Al Gmuer, modeled the Super Friends' iconic base of operations on the terminal, and the fictional building was later incorporated into the DC Comics universe as the headquarters of the Justice League.

4. The Daily Planet Building and Metropolis

Superman co-creator Joe Shuster once worked as a newsboy, and the inspiration for the fictional Daily Planet newspaper building where Clark Kent works is believed to come from the former headquarters of the Toronto Star, which was called the Daily Star when Shuster worked there. Shuster himself has indicated that Toronto was the visual inspiration for Metropolis, though there isn't anything even remotely resembling the iconic globe that tops the Daily Planet headquarters to be found in the Toronto skyline.

5. Peter Parker's House

Right from the start, Spider-Man co-creators Stan Lee and Steve Ditko chose the Forest Hills neighborhood of Queens, NY, as the home of everyone's favorite webslinging hero, Peter Parker. However, it wasn't until a 1989 issue of The Amazing Spider-Man that his exact address was specified as 20 Ingram Street. While the real-world house at 20 Ingram Street is significantly larger than the modest home Peter Parker lived in with his Aunt May in the comics, the buildings do share one very notable, mind-blowing connection: they're both the home of the Parker family. For more than a decade before Peter Parker's home address was outed in comics, a family with the “Parker” surname had lived in the house at 20 Ingram Street. It's unknown whether the series' writer at the time, David Michelinie, was aware of the coincidence when he chose that address for Peter Parker.

(Bonus: One of the Parker family's neighbors on Ingram Street in real-world Forest Hills is the Osborne family, who are apparently friendly with the Parkers.)

6. Nightwing's Cloisters HQ

In the late 2000s, former Batman sidekick Dick Grayson (who had switched from Robin to the more adult-sounding moniker of Nightwing when he went solo years earlier), took up residence at The Cloisters Museum in New York City's Washington Heights neighborhood. Serving as the museum's curator by day, he prowled New York by night, and even had certain portions of the building remodeled to suit his secret-base needs. In the real world, the medieval-styled Cloisters hasn't served as the home to any superheroes that we know of, but it still strikes an impressive silhouette at the northern tip of Manhattan.

7. The ­All-Star Squadron's Perisphere HQ

The World War II-era adventures of DC's superheroes were rewritten in this early-'80s series which had the old-school versions of Superman, Batman, Wonder Woman, and a long list of other Golden Age heroes operating out of the Trylon and Perisphere in Flushing Meadows, Queens. Built for the 1939 World's Fair, the futuristic pyramid and sphere shapes of the Trylon and Perisphere, respectively, seemed like appropriate headquarters for the team of classic characters—though they were dismantled at the end of the event. All-Star Squadron suffered a similar fate, with the series ending in 1987.

8. Yancy Street

The Fantastic Four's rock-skinned, blue-eyed heavyweight The Thing has never shied away from an opportunity to remind readers that he came from Yancy Street, a tough neighborhood on the Lower East Side of Manhattan. While there isn't any Yancy Street to be found in the real-world version of that neighborhood, there is a Delancey Street—which just so happens to be in the neighborhood where Fantastic Four co-creator Jack Kirby grew up. Given how many real-world details from creators' lives made it into these early Marvel comics, it's assumed by many comics experts that Yancy Street was indeed a stand-in for Delancey Street, which spans the Lower East Side from the Bowery to the East River.

Bonus! Address On File, No Such Resident

Some other famous fictional landmarks that have addresses in the real world but weren't inspired by any existing buildings include the Fantastic Four's Baxter Building, located at the corner of 42nd Street and Madison Avenue; Iron Man's Stark Tower, near Columbus Circle in Manhattan; and the Justice Society of America's former headquarters in Morningside Heights, Manhattan.
