After a recent trip to Florence, Italy, left me with more than my fill of classical and medieval artwork, I started looking for something different in my next art museum experience. I wanted something raw, personal and a little strange.

That’s how I ended up at the Prinzhorn Collection in Heidelberg, a small museum with a big emotional punch. It focuses on art made by psychiatric patients, mostly between 1840 and 1945.

The museum is named after Dr. Hans Prinzhorn, a psychiatrist and art historian who began collecting the work while treating patients at Heidelberg University’s clinic around 1920. He believed their creations should be viewed as art, not just medical curiosities.

The heralded German city about an hour’s drive from Kaiserslautern is a popular destination, so I was surprised that I and most of the people I asked had never heard of this museum, which is an easy walk from Bismarckplatz, near the entrance to the Old Town.

Parking was a breeze, which is not something I usually say about city museums. Since it is located on the grounds of the university’s psychiatric hospital, underground garages offer plenty of room.

Upon admission, I was given two English-language guides, one for the permanent collection and one for the temporary exhibition titled “Who Am I?”

The latter explores how people understand and express identity through art, with a special focus on artists diagnosed with schizophrenia and memory disorders.

It runs through April 19 and includes some of the most memorable work in the museum. Some pieces are conceptual, while others feel intensely personal.

One that stuck with me was a hand-sewn jacket by Agnes Richter, a seamstress who was committed in 1893. She embroidered autobiographical phrases into the fabric in tight spirals of old German script.

The stitching covers every inch, inside and out. It feels like a wearable testament from a woman determined not to be erased by her mental illness or by a world that may not have known what to do with her.

The permanent exhibition is small but compelling. It includes a rotating selection from more than 40,000 paintings, drawings and sculptures that range from fragmented to surprisingly refined.

Some artists featured in the permanent collection also had work displayed in the temporary show. I eventually started connecting with the voices of various creators.

One piece in the main exhibition that held my attention was a deceptively simple drawing displayed inside a darkened box with a small viewing hole.

A button allows viewers to change the lighting angle. From the front, it shows a peaceful garden scene, but when lit from behind, a hidden image of a human skull and brain appears through the paper.

Many of the works in the Prinzhorn Collection were created by people who had been hospitalized in Heidelberg. That makes the setting feel especially intimate, as if the art is still in conversation with the place it came from.

The collection’s history adds further weight to the experience. Much of the art was labeled “degenerate” by the Nazis in the 1930s and nearly destroyed. It survived by getting “lost” in university storage.

I spent just over an hour at the museum, although I can imagine a longer stint for visitors who have someone accompanying them, bouncing their thoughts off each other as they browse.

Regardless of the duration, the experience lingers long after you leave.

If you’re planning a trip to Heidelberg, carve out time to visit this unobtrusive spot, whose quiet quirkiness makes it one highly memorable mind trip in a city known for producing some of the world’s greatest minds.
