Why are so many of us fascinated with abandoned buildings? After all, they’re creepy, and some are even downright terrifying, so it’s truly baffling why we love them so much. Some folks will even risk their safety just for a glimpse inside these dilapidated structures. If you have, you're not alone, I have done it too! Over the years, we have covered many abandoned buildings in Indiana, some with incredible stories of why they have been left vacant for so long. One of the most fascinating is Horace Mann High School in Gary, which has been left deserted for over two decades. As arguably the most iconic decaying building in the state, this abandoned high school in Indiana has a long and fascinating tale to tell. 

If you love creepy content, Only In Your State’s Vacant series – which partners with talented photographer Johnny Joo – explores a dozen other fascinating abandoned places just waiting to be discovered. 

Editor’s Note: Due to the nature of abandoned destinations, many of the places featured in this series are off-limits to visitors or have actually been demolished. We do not condone trespassing and other illegal activity but rather encourage readers to enjoy learning about these fascinating destinations.

In the early 20th century, Gary, Indiana, was a bustling hub during the Industrial Steel Revolution. As the epicenter of the Rust Belt, the town attracted thousands of folks vying for a chance of a better life for their families.

The influx of European immigrants, southern Black Americans, and successful businesspeople resulted in a population of over 100,000 residents by 1930. Consequently, the town's infrastructure reflected its success, leading to prominent educational institutions such as Horace Mann High School.

However, due to enormous challenges in the town's political, economic, and social structure, its fall was imminent. Naturally, as the bustling city declined, so did its institutions within its limits. 

The auditoriums and halls of Horace Mann High School were once filled with laughter, chatter, and echoes of its students, faculty, and staff. However, more than 20 years ago, the school was left abandoned and only deafening silence has encapsulated those spaces today. Completed in 1928, this towering school building housed a maximum of approximately 2,500 students, and it featured incredible facilities, which was a testament to the town in which it dwelled. Some include a massive auditorium, two gymnasiums, multiple science labs, as well as outdoor fields and common spaces.

Unfortunately, with the decline of the steel industry along with the change in the diversity of Gary, residents fled the city in droves. As a result, by 2003, the population of Horace Mann High School dwindled to just under 550 students. With only a graduating class of 72 students and budgetary constraints, the school board finally closed this once-prosperous institution in the summer of 2004. 

It’s shocking to think that this school was built as a reflection of the thriving town of Gary, but like the town, it’s now a stark reminder of the prosperity that has been lost and forgotten. Though the building is decaying, vandalized by graffiti artists, and nature is reclaiming many of the outdoor spaces, there is no denying that the school was an emblem of pride for the community. Past students rave about the fond memories they had here. In fact, a student of Class of 74 stated that it was the “BEST school in the city of Gary” and “Had the BEST time at Horace Mann.” 

There is no doubt that the school has left a lasting legacy on the students who once walked the hallways. What’s more, there are various online communities dedicated to keeping the memories of the grand institution alive. Moreover, the alumni have organized class reunions as well as other social events throughout the years. Though this school will never be resurrected, there is no denying that it was and has remained a symbol of pride for those who walked through the halls. It’s comforting to know that this historic institution will forever be etched in the fabric of the hearts of the alumni as well as serve as an iconic symbol for the once prosperous city of Gary Indiana.

As mentioned, we do not encourage trespassing; instead, take a look at some more incredible images captured of the crevices of this abandoned high school in Indiana.
