Building 23 at the Pilgrim State Hospital was the site of thousands of the crude, 45 minute, brain surgeries known as a lobotomy. These operations started at the hospital in the 1940's and continued into the 70's. Often times these procedures would leave the individual lifeless. Pedlar Pedlar

A lobotomy was the leading treatment for mental illness until 1980's when drugs became available. Once pharmaceuticals reached the public not only did the procedure go away, so did the need for such facilities. But what is left behind?

Many say the old site holds a lot of spirit energy, perhaps of former patients. There is a graveyard on the property and many buried here are those that once endured a lobotomy. Many of their graves are simply marked with a number and no name. Pedlar Pedlar
