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

A lobotomy was the leading treatment for mental illness until the 1980s 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 from 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
