Does anyone know what it is like in a workhouse? my friend went to the Plymouth workhouse in Minnesota.?

I tried googling it online, but didn't really give me any ideas. I'm probably looking in the wrong place; He went to the Plymouth workhouse in Minnesota. the city is Plymouth, it is an adult corrections facility. can anyone give me an idea of what it's like and what does the inmates do while they serve their time? any answers is appreciated. thanks
